Fix RELEASE_ASSERT_NOT_REACHED on CoverInitializedName used as a value

A CoverInitializedName such as `{ a = 0 }` (object shorthand with default) is
only valid when the enclosing object literal is refined into a destructuring
pattern. When such an object literal is instead consumed as a real value -- the
base of a member access, call, computed access, or tagged template, e.g.
`( {... { a = 0 }. b = 1 } )` -- the pending CoverInitializedName error was
discarded by a later assignment, so no SyntaxError was raised and the
AssignmentPattern property value reached bytecode generation, hitting
RELEASE_ASSERT_NOT_REACHED in Node::generateExpressionByteCode.

Report the pending CoverInitializedName as an early SyntaxError in the two
LeftHandSideExpression member-access loops the moment the base is consumed as a
value, since it can no longer be refined into a pattern.

-## Prerequisites
 
-#### On Ubuntu Linux
+Escargot is a lightweight JavaScript engine developed by [Samsung](https://github.com/Samsung), designed specifically for resource-constrained environments. It is optimized for performance and low memory usage, making it ideal for use in embedded systems, IoT devices, and other applications where resources are limited.
+
+Key features of Escargot include:
+* **ECMAScript Compliance**: Escargot supports a significant portion of the latest ECMAScript version ([ECMAScript 2025](https://262.ecma-international.org/16.0/)), ensuring compatibility with modern JavaScript standards while maintaining a lightweight footprint.
+* **Memory Efficiency**: The engine is designed with memory constraints in mind, making it suitable for devices with limited RAM and storage.
+* **Performance Optimization**: Escargot implements various optimization techniques to ensure fast execution of JavaScript code, even on low-power devices.
+* **Extensibility**: The engine can be customized and extended to meet the specific needs of different applications, providing flexibility for developers.
+
+Escargot is an open-source project that allows developers to contribute to its development or use it in their own projects, while also powering several services in Samsung products. The engine's design prioritizes simplicity and efficiency, making it an excellent choice for developers working in embedded or resource-limited environments.

 ```
 
-### Benchmarks
+## Debugger
 
-Test run for each benchmark (Sunspider, Octane, V8, Chakracore, test262,
-SpiderMonkey, etc.):
+Make sure Escargot is built with the `-DESCARGOT_DEBUGGER=1` flag (off by default) enabled;
+then start Escargot with the `--start-debug-server` option.
+
+### Connect using a debugger client
+
+- Escargot python debugger
+  - run `./tools/debugger/debugger.py`; It will automatically connect to a debug server on the default port `6501`
+  - run `./tools/debugger/debugger.py --help` for a list of options
+- [Visual Studio Code extension](https://github.com/Samsung/escargot-vscode-extension/?tab=readme-ov-file#how-to-use)
+- Chrome Devtools `⚠️ Early in development ⚠️`
+  - Initial setup:
+    - Navigate to [chrome://inspect](chrome://inspect)
+    - Make sure *Discover network targets* is enabled; click configure
+    - Add `localhost:6501` as a target; click Done
+  - Usage:
+    - The started debug server will be listed in the *Remote Target* list (If it is not, the page may need to be reloaded using the browser reload button)
+    - Click `inspect`
+    - A new window with the Chrome Devtools debugger UI will open
+
+## Testing ✅
+
+Escargot supports various benchmark sets, which can be run using the [tools/run-tests.py](https://github.com/Samsung/escargot/blob/master/tools/run-tests.py) script.
+
+| Benchmark | flag |
+| --- | --- |
+| SunSpider 1.0.2 | `sunspider` |
+| [Octane 2.0](https://github.com/chromium/octane.git) | `octane` |
+| [test262](https://github.com/tc39/test262.git) | `test262` |
+| [Web Tooling Benchmark](https://github.com/v8/web-tooling-benchmark) | `web-tooling-benchmark` |
+| SpiderMonkey (vendor-made) | `spidermonkey` |
+| ChakraCore (vendor-made) | `chakracore` |
+| V8 (vendor-made) | `v8` |
+
+Run each benchmark separately or all together as shown below:
 ```sh
-tools/run-tests.py --arch=x86_64 spidermonkey test262 v8
+tools/run-tests.py --engine=./out/linux/x64/release/escargot web-tooling-benchmark
+tools/run-tests.py --engine=./out/linux/x64/release/escargot spidermonkey test262 v8
