Add interactive TUI browser for tasks, contracts, and files (makima view) (#7)

* feat(tui): Implement fuzzy search with real-time filtering and highlighting

Adds comprehensive fuzzy search functionality to the TUI browser:

## Fuzzy Matching (fuzzy.rs)
- FuzzyMatcher wrapper using SkimMatcherV2 from fuzzy-matcher crate
- fuzzy_match() returns score and matched character indices
- fuzzy_match_all() supports multi-term search (space-separated)
- Recency-aware scoring to boost recent items in results
- Unit tests for all matching scenarios

## App State (app.rs)
- FilteredItem struct with index, score, and matched_indices
- apply_filter() uses fuzzy matching with score-based sorting
- match_count() and has_no_matches() helper methods
- Results sorted by match score (highest first)

## List View (list_view.rs)
- Highlighted matched characters in search results
- Yellow bold styling for matched chars
- Status icons with color coding

## Search Input (search_input.rs)
- Real-time match count display (X/Y matches)
- Visual feedback for no matches (red border)
- Placeholder text when search is empty
- Active search mode indication (yellow border)

## Event Handling (event.rs)
- Arrow key navigation while in search mode
- Ctrl+K/J for vim-style navigation during search
- Delete key support alongside backspace
- Ctrl+U to clear search query
- Tab toggles preview while searching
- Escape clears search and exits search mode

* fix(tui): Fix module exports and main binary integration

- Update mod.rs to properly export app, event, fuzzy, and ui modules
- Add run() function for TUI entry point
- Fix run_view() to use ViewCommand enum instead of ViewArgs
- Fix event handling to use poll_event and handle_key_event
