* feat: add catchtable-sniper skill
* Make the Catchtable skill loadable and discoverable
The submitted skill landed under skills/ without YAML frontmatter, which broke the repo's auto-discovery contract and Codex skill loading. Move it to the root-level skill layout, add the required metadata block, and document the feature in the main README plus a dedicated guide so the PR ships in a usable state.
Constraint: This repository auto-discovers skills from root-level directories only
Constraint: Skill manifests must start with YAML frontmatter for Codex to load them
Rejected: Keep the nested skills/catchtable-sniper layout | validate-skills and the repo's documented convention reject it
Rejected: Add only README links without a feature guide | would create a broken documentation target
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Future skill PRs should follow docs/adding-a-skill.md and place each skill in its own root directory
Tested: node --test scripts/skill-docs.test.js
Tested: ./scripts/validate-skills.sh
Tested: git diff --check
Not-tested: End-to-end Catchtable reservation completion on a logged-in account
