- Implemented tiered search strategy using synchronous literal matching for immediate results and debounced asynchronous fuzzy matching to prevent input blocking.
- Cached session search data and introduced an indexed `FuzzyText` structure to reduce redundant string processing.
- Added comprehensive test suite verifying search convergence, stale task orphaning, and selection stability.
- Enhanced `tui` fuzzy matching utilities to support prebuilt search indexes for improved multi-match performance.
