Introduce first-class support for rendering text and markup via Typst (optional dependency) (#4681)
* feat: add TypstMobject and TypstMathMobject for first-class Typst support

Implement the initial TypstMobject proposal (see agents/typst.md):

- TypstMobject: renders arbitrary Typst markup to SVG via the 'typst'
  Python package (self-contained Rust binary, no system install needed),
  then imports through SVGMobject.
- TypstMathMobject: convenience subclass that wraps input in Typst math
  delimiters ($ ... $).

Pipeline: user string → wrap in minimal Typst document (auto-sized page,
transparent background) → write .typ file → compile to SVG via
typst.compile() → import via SVGMobject → scale/center/recolor.

Key details:
- Compilation helper in manim/utils/typst_file_writing.py with SHA-256
  content-hash caching (same scheme as the LaTeX pipeline).
- font_size property mirrors SingleStringMathTex: compile at fixed 11pt,
  scale after import using initial_height / SCALE_FACTOR_PER_FONT_POINT.
- init_colors() recolors black submobjects to self.color (Typst default
  fill is black), preserving any explicit Typst colors.
- path_string_config enables curve subdivision for smooth animation.
- 'typst' added as optional dependency group in pyproject.toml.
- 10 tests covering creation, font_size, caching, preamble, and repr.

* feat(typst): add sub-expression selection via {{ }} groups and .select()

- Override modify_xml_tree in Typst to convert data-typst-label
  attributes to id attributes before svgelements parsing (avoids
  attribute inheritance issue with data-* attributes)
- Add Typst.select(key) method accepting str labels or int indices
  to retrieve VGroup sub-expressions from id_to_vgroup_dict
- Implement {{ }} double-brace preprocessor on TypstMath:
  - {{ content }} → manimgrp("_grp-N", content) (auto-numbered)
  - {{ content : label }} → manimgrp("label", content) (named)
  - Skips {{ }} inside string literals and [...] content blocks
  - Uses math-mode call convention (no # prefix) to keep args in
    math mode
- Auto-inject manimgrp preamble when groups are detected
- Add 12 new tests covering label mapping, nesting, select(),
  error handling, and preprocessor edge cases

* Remove unneeded assert line

* Generalize some more critical hard-coded LaTeX assumptions

* Fix syntax error

* Support Typst labels in existing APIs

* Add ManimTextLabel typing alias

* Preserve Typst SVG stroke widths by default

Add tests for edge lookup in GenericGraph.__getitem__() (#4753)
GenericGraph.__getitem__ only handled vertex lookup. Passing a 2-tuple
(u, v) to retrieve an edge mobject raised a KeyError against the
vertices dict instead of looking up self.edges.

Route tuple keys of length 2 to self.edges so that g[(u, v)] returns
the edge mobject, consistent with how edges are stored internally.

Adds a test covering vertex lookup, edge lookup (Graph), and edge
lookup (DiGraph).

Fixes #3798

Add regression tests for four recent fixes in vectorized_mobject.py (#4750)
* Add regression tests for four recent fixes in vectorized_mobject.py

Adds four regression tests for fixes that landed without tests in the same PR:

  * 21cf9998 (PR #4630, fixes #3569 + #4629) -- IndexError in
    `get_nth_subpath` when `path_list` is empty; ensure it always returns
    a NumPy array.

  * f6cdb547 (PR #4219) -- `add_points_as_corners` silently dropped a
    single new point when called on a VMobject whose last subpath was
    complete.

  * 3d029c12 (PR #4320, fixes #4255) -- `pointwise_become_partial` cleared
    the target's points when the source had no cubic curves, surfacing as
    `Arrow3D.get_start()` / `get_end()` returning the origin after a
    `Create` animation.

  * 429f25328 (PR #4694) -- `scale(scale_stroke=True)` on a compound
    VMobject propagated the parent's scaled stroke width to every
    submobject, overwriting submobjects with their own (e.g. zero) stroke.

Each test reproduces the original failing condition at the unit level
and asserts the post-fix behavior. Validation: every test was confirmed
to fail when the corresponding fix is reverted on the source file, and
pass when the fix is restored.

4 tests, ~0.2s runtime. Tests go in the existing files
`tests/module/mobject/types/vectorized_mobject/test_vectorized_mobject.py`
(three tests, adjacent to their topically-related siblings) and
`tests/module/mobject/types/vectorized_mobject/test_stroke.py` (one test,
next to the existing `test_stroke_scale`).

Add unit tests for module-level color helpers in manim/utils/color/core.py (#4749)
* Add unit tests for module-level color helpers in manim/utils/color/core.py

Adds tests/module/utils/test_color_helpers.py covering the standalone
helper functions exported from manim.utils.color.core (color_to_rgb,
color_to_rgba, color_to_int_rgb, color_to_int_rgba, rgb_to_color,
rgba_to_color, rgb_to_hex, hex_to_rgb, invert_color, color_gradient,
interpolate_color, average_color, random_bright_color, random_color)
and the RandomColorGenerator class.

Before this PR, only the ManimColor class itself was tested
(via tests/module/utils/test_manim_color.py); the standalone helpers
had zero direct test coverage. Coverage on manim/utils/color/core.py
goes from 71% to 80% (line+branch), and 17 of the 18 testable symbols
in the file's __all__ are now exercised. The only deferred symbol is
get_shaded_rgb, which concerns lighting math rather than color
conversion and is better suited to a follow-up.

42 tests, ~0.3s runtime, no new dependencies.

fix: MathTex double-brace splitting no longer fires on natural LaTeX }} (#4602)
* fix: replace double-brace splitting regex with state-machine parser

The previous re.split(r'{{|}}', ...) call split on any occurrence of
{{ or }} in the input string, which broke strings whose only }} came
from closing two nested LaTeX brace groups (e.g. ^{\frac{Mq}{M+m}}).

The new _split_double_braces() static method uses a character-level
state machine with three guards:

* Escape priority: \\ is consumed before \{ / \}, so \\}} is
  correctly read as an escaped backslash followed by a real }}, not
  misinterpreted as \ + \} + lone }.

* Whitespace-gated opener: {{ is only treated as a Manim group opener
  at the start of the string or after whitespace. Naturally-occurring
  {{ in LaTeX is usually preceded by non-whitespace (e.g. \frac{{{n}}}
  or a^{{2}}), so this eliminates the most common false positives.

* Depth-tracking closer: inside a Manim group, }} only closes the
  group when the inner brace depth is zero, so {{ a^{b^{c}} }} is
  handled correctly and nested LaTeX }} cannot trigger an early close.

Fixes #4601.

* docs: document double-brace whitespace requirement

Add a Notes section to the MathTex docstring explaining:
- how {{ }} splits a string into submobjects
- that {{ must be at start-of-string or preceded by whitespace
- that this leaves natural LaTeX like \frac{{{n}}}{k} untouched
- the { { ... } } escape hatch when a split is not wanted

Apply the same explanation to the double-brace paragraph in
docs/source/guides/using_text.rst.

* fix: use r-string for _split_double_braces docstring, halve backslash escaping

Enable strict=True for zip() where safe (#4547)
* sub_alphas is derived directly from to_update so they're guaranteed to be of the same length.

* self.shapes is initialised as a direct copy of the mobject, guaranteed to be of same length.

* linspace in this case guarantees both arrays are of equal size (self.n_segments).

* Any transformation already requires that each datapoint in the first tuple has a corresponding datapoint in the second (ie same length)

* Replaced arange with linspace, eliminates risk of floating point errors and forces rgbas and offset to be the same size for strict=True

* all_arc_configs is either defined specifically by length of point_pairs or strictly forced to be the same length (n). In any case they'll always be the same length so strict=True works.

* There should always be an equal amount of start and end anchors; radius_list is defined directly from the length of vertex_group; both outer_vertices and inner_vertices posess n vertices.

* boundary_times always contains has an even length so both 'slices' in the zup function are the same length.

* colors_in_gradient is defined to be the same length as p_list_complete; labels and parts are seemingly user inputs with no guarantee of equal length; val_range is defined to be same lenght as self.bar_names; however there's no authentication that self.values has a fixed length after it's been defined ie user can append to the list creating a mismatch between len(self.values) and len(self.bars)

* In most cases here, the tuples are either defined to be of same length or manipulated to be by the align_data function. In the match_points function there is currently no validation to ensure both mobjects are the same length.

* Reverting _add_x_axis_labels() zip() function back
to strict=False due to failing test cases

* Reverted strict zip usage

* color_gradient is defined to be same length as p_list_complete & within _add_x_axis_labels we define val_range to be the same length as self.bar_names

* align_data and lock_matching_data have no validation to ensure tuples in the zip() function are of the same length. Every other time zip() is used here it is generally immediately manipulating or explicitly defining the tuples to be of same length

* All tuples in zip() functions here are either clearly the same size or manipulated to be the same size using the make_even function.

* The tuples in the zip() function will clearly be of equal length, the second tuple is simply a cyclic shift of the first.

* In the ingest_submobjects function arrays is a one to one mapping of attrs so they are guaranteed to have equal lengths.

* Every usage of zip() consists of tuples that are either manipulated to be equal size or defined to be equal size.

* the zip() function in bezier_remap will always consist of equal length tuples as current_number_of_curves is read directly from the shape of bezier_tuples and is used to dictate the size of split_factors.

* The zip() function color_gradient() will always consist of equal length tuples as floors is defined directly from alphas (which also defines alphas_mod1)

* The tuples in the zip() function in adjacent_n_tuples will always be the same length so strict=True.

* The find_intersection() contains a zip() function that has been set to strict=True. While it is technically possible to pass tuples to this function that are *not* the same length, this would result in generally unexpected behaviour anyway.

* Changed zip() function to have strict=True in __init__() as custom_labels is dependent on tick_range so guaranteed to have the same length.

* Several instances of zip() set to strict=True. In add_coordinates we have axis manipulated to be the same length as tick_range. In get_riemann_rectangles() we have colors dependent on of x_range_Array forcing them to be the same length. Finally in plot_line_graph()  it is clearly intended that all inputs used in the zip() function are of the same length (except possibly z which may not exist and will be made equal length to x); while it is not guaranteed they will be the same length this would cause unintended behaviour.

* zip() function bool changed to strict=True in all these test cases. Most test cases either a) hardcode two things to be the same length, b) verify things are the same length before the function or c) explicitly exist to check whether two things are the same length.

Prevent mutation of about_point in apply_points_function_about_point - Fixes #4445 (#4478)
* Add regression tests for about_point view mutation issue

This adds regression tests for issue #4445 where using get_vertices()[0]
as about_point in transformation methods would cause incorrect results
due to numpy array view mutation.

Tests added:
- test_rotate_about_vertex_view
- test_scale_about_vertex_view
- test_stretch_about_vertex_view
- test_apply_matrix_about_vertex_view
- test_opengl_rotate_about_vertex_view (OpenGL was not affected by the bug)

Related to #4445

* Fix about_point view mutation in apply_points_function_about_point

When about_point parameter receives a numpy array view (e.g., from
get_vertices()[0]), the in-place operation `mob.points -= about_point`
would mutate the view, corrupting the transformation calculation.

This fix copies about_point before using it to prevent view mutation.

The OpenGL renderer was not affected by this bug because it uses
`arr - about_point` (creates temporary) instead of `arr -= about_point`
(mutates in-place).

Fixes #4445
