- Migrated native bindings from TypeScript wrappers to NAPI-RS generated modules with auto-generated type definitions and runtime enums.
- Replaced chunk tree API with stateful ChunkState class supporting render, edit, and resolve operations with improved error handling.
- Converted callback signatures to error-first pattern (error, result) for shell, PTY, glob, and grep operations.
- Introduced type-safe enums for MacOSAppearance, GrepOutputMode, KeyEventType, ImageFormat, and AstMatchStrictness replacing string literals.
- Refactored chunk tree implementation with dedicated modules for edit, indent, resolve, and state management with comprehensive validation.
- Moved clipboard utilities from native bindings to coding-agent package with improved OSC 52 and Termux compatibility.
- Migrated test mocking from bun:test mock API to vitest spyOn pattern across 9 test files.
- Extracted mock setup logic into reusable helper functions with Symbol.dispose cleanup pattern.
- Replaced manual beforeEach/afterEach and try-finally blocks with TypeScript 5.2 using declarations.
- Removed 178 lines of boilerplate mock initialization and restoration code from test suite.
- 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.
