…cking (#56)

* fix: resolve E2E test 'Unknown command' errors and improve UE log checking

- Updated Python listener command mappings to handle server-layer-only tools
- Added proper error responses for MCP server layer tools (undo/redo/history/checkpoint/placement_validate)
- Fixed E2E test UE log checking by reading log file directly instead of through MCP
- Enhanced comprehensive test with intelligent actor cleanup (check existence before deletion)
- Added server-layer tool awareness to prevent inappropriate direct Python calls

* fix: address code review feedback for file descriptor cleanup and magic numbers

- Use try-finally block for proper file descriptor cleanup in UE log checking
- Extract magic number 50000 to named constant LOG_BUFFER_SIZE
- Ensures proper resource management even if file operations fail

Addresses GitHub Copilot code review feedback on PR #56

* enhance: organize test actors in 'Test' folder for comprehensive cleanup

- Updated test-socket-snapping.js to use unique timestamped actor names
- Added 'Test/SocketTest' folder organization for socket snapping test actors
- Updated test-comprehensive-mcp.js to use 'Test/Building/*' folder structure
- Enhanced E2E test runner with comprehensive test actor cleanup
- Cleanup now detects and removes all test actor patterns (Wall*, Foundation, WallSegment_*, etc.)
- Prevents test actor accumulation across multiple E2E test runs

Benefits:
- No more duplicate named actors left behind
- Easy identification of test artifacts in World Outliner
- Comprehensive cleanup ensures clean project state
- Better test isolation and repeatability

* reset calibration level

* completely reset Calibration level

* fix: resolve E2E test cleanup issues - no more leftover actors

Root Cause Analysis:
- MCPClient had 30-actor limit in Python listener, missing test actors beyond limit
- SocketActor1/SocketActor2 not included in cleanup patterns
- Test folder structure remained in World Outliner after tests

Solutions Implemented:
- Increased MCPClient level_actors limit from 30 to 100 actors
- Added 'SocketActor' to testActorPatterns for comprehensive cleanup
- Added Test folder structure cleanup via python_proxy
- Enhanced cleanup logging with detailed actor deletion tracking

Test Results:
✅ E2E cleanup now removes ALL 6 test actors (Wall*, Door*, Foundation, SocketActor*)
✅ Test folder structure automatically cleaned when empty
✅ Calibration level remains unchanged after test completion
✅ No manual cleanup required between test runs

The E2E testing framework now maintains a completely clean project state,
ensuring reliable and repeatable test execution without any leftover artifacts.
