feat(coding-agent): added fuzzy token matching in coding-agent components

- Added fuzzy token matching in agent-dashboard, state-manager, and tree-selector, replacing lowercased checks.
- Added search-query state and fuzzy-filter helpers to hook, oauth, and user-message selectors for query filtering.
- Updated filtered selectors to render match results, status lines, no-match text, and move selection within results.
- Added `overflowSearch` and filter state to `SelectList`, switching overflowing list matching to fuzzy checks.
- Configured `SelectList` input flow and fixed cancel so Escape/Ctrl+C closes lists when no matches exist.
- Updated changelogs and added tests for fuzzy-filter behavior in hook, oauth, user-message, and list selectors.
