- Fixed OSC 11 background color detection to handle partial escape sequences that arrive mid-buffer, preventing user input from being swallowed.
- Fixed race condition where overlapping OSC 11 queries would be incorrectly cancelled by DA1 sentinels from previous queries by implementing a query queueing mechanism.
- Refactored OSC 11 query handling to use queuing instead of immediate restart, improving robustness of terminal appearance detection.
- Added comprehensive test coverage for terminal appearance detection including partial buffer handling, query queueing, and debouncing behavior.
- Added test cases for theme auto-detection to verify terminal-reported appearance takes precedence over environment variables and platform-specific detection.
