docs: Update llms_project_context.txt to reflect CI/CD and tooling fixes (Issue #34)

This commit updates the project context file to reflect the recent, critical fixes to the development workflow and tooling.

**Key Changes:**
- **Project Status**: Updated to reflect the new, fully synchronized CI/CD pipeline and tooling.
- **Critical Workflows**: Enhanced the "Automated LLM Code Quality Protocol" section to include details about the `.prettierrc.json` file and the correct `quality:fix` script order.
- **Technical Standards**: Updated the "Testing & Quality" section to be more explicit about the ESLint/Prettier integration.
- **General Cleanup**: Ensured all information is consistent with the latest project state.

This ensures that all developers (human and AI) have access to the most current and accurate project documentation.

 # Auto-fix workflow (.github/workflows/auto-fix.yml)
 # - Runs before main CI pipeline
-# - Automatically fixes ESLint and Prettier issues
+# - Automatically formats and fixes ESLint issues
 # - Commits fixes back to branch with [auto-fix] tag
 # - Prevents CI failures from LLM code generation

 **LLM Development Workflow:**
-1. **Generate Code**: LLMs can generate code without worrying about minor linting issues
-2. **Auto-Fix Triggers**: Push/PR automatically triggers auto-fix workflow
-3. **Automatic Fixes**: ESLint --fix and Prettier --write applied automatically
-4. **Auto-Commit**: Fixed code committed back to branch with [auto-fix] message

+1. **Generate Code**: LLMs can generate code without worrying about minor linting or formatting issues.
+2. **Auto-Fix Triggers**: Push/PR automatically triggers the auto-fix workflow.
+3. **Automatic Fixes**: Prettier and ESLint are run in the correct order to automatically format and fix the code.
+4. **Auto-Commit**: Fixed code is committed back to the branch with an `[auto-fix]` message.
+5. **CI Validation**: The main CI pipeline runs on the *already fixed* code, ensuring a smooth and reliable build.
 
 **Enhanced Scripts Available:**

-- **API Compatibility** - When changing public interfaces, update all consumers
-- **Test Cascade** - Run tests for modified component AND all dependent components
-- **Breaking Change Documentation** - Clearly document any API changes in commit messages
