Fix inconsistent .gitignore/.rooignore handling in codebase indexing

[roomote-agent]

This PR fixes the inconsistent .gitignore and .rooignore handling in the codebase indexing system reported in issue #5655.

Problem

• Code indexing loaded .gitignore in CodeIndexManager but applied .rooignore separately in DirectoryScanner
• No fallback to .gitignore when .rooignore was missing/empty
• .gitignore and .rooignore handled by completely different systems
• node_modules and similar folders indexed when .rooignore missing

Solution

• Created UnifiedIgnoreController that combines both .gitignore and .rooignore processing
• Implemented fallback behavior: .gitignore used when .rooignore is missing or empty
• Updated CodeIndexManager and DirectoryScanner to use unified system
• Enhanced list-files service to support .rooignore patterns

Key Features

• Hierarchical .gitignore support
• File watching for automatic reloads
• Consistent API for file validation and path filtering
• Comprehensive test suite with 23 test cases
• Backward compatibility maintained

Testing

• All existing tests pass (402 tests total)
• New comprehensive test suite covers all functionality
• Fixed VSCode mocks in test files

Closes #5655

Important

Introduces UnifiedIgnoreController for consistent .gitignore and .rooignore handling in codebase indexing, with comprehensive tests and updates to existing logic.

• Behavior:
  • Introduces UnifiedIgnoreController to handle .gitignore and .rooignore with fallback to .gitignore if .rooignore is missing or empty.
  • Updates CodeIndexManager and DirectoryScanner to use UnifiedIgnoreController for consistent ignore handling.
  • Enhances list-files service to support .rooignore patterns.
• Testing:
  • Adds comprehensive test suite for UnifiedIgnoreController with 23 test cases.
  • Updates existing tests in manager.spec.ts, scanner.spec.ts, and gitignore-integration.spec.ts to reflect new ignore handling.
• Misc:
  • Removes old ignore handling logic from list-files.ts and replaces it with UnifiedIgnoreController.

I see this PR was automatically closed due to being created by @roomote-agent before 2025-07-16. I will review the changes and continue working on the .gitignore/.rooignore handling fix. The work appears to be substantial with a UnifiedIgnoreController implementation and comprehensive tests.

[roomote]

I have successfully reopened this PR and verified that the implementation is complete and working correctly.

✅ Implementation Summary

The PR successfully addresses the inconsistent .gitignore/.rooignore handling issue (#5655) with a comprehensive solution:

🔧 Key Features Implemented:

• UnifiedIgnoreController: New centralized controller that handles both .gitignore and .rooignore patterns
• Fallback Behavior: Automatically falls back to .gitignore when .rooignore is missing or empty
• Hierarchical Support: Supports multiple .gitignore files up the directory tree
• File Watching: Automatic reloading when ignore files change
• Consistent API: Unified interface for file validation and path filtering

📁 Files Updated:

• src/core/ignore/UnifiedIgnoreController.ts - New unified controller implementation
• src/services/code-index/manager.ts - Updated to use unified ignore handling
• src/services/code-index/processors/scanner.ts - Updated DirectoryScanner integration
• src/services/glob/list-files.ts - Updated list-files service integration
• src/core/ignore/__tests__/UnifiedIgnoreController.spec.ts - Comprehensive test suite (23 test cases)

✅ CI Status:

All checks are passing:

• Compilation: ✅
• Unit tests (Ubuntu/Windows): ✅
• Integration tests: ✅
• Code analysis: ✅
• Security checks: ✅

The implementation is ready for review and merge. This resolves the core issue where .gitignore and .rooignore were handled by different systems, ensuring consistent behavior across the entire codebase indexing pipeline.
