refactor(types): eliminate all as any type assertions (30 → 0)

- Replace MouseEvent-only handlers with MouseEvent | KeyboardEvent unions in multi-select and ChatTabBar
- Define LegacyInstalledPlugin type for backward compatibility in plugin-api
- Create getTokenValue() helper for type-safe theme token access in AppearanceTab
- Define ModelConfig interface for model configuration type safety in modelProvider
- All modifications maintain exact business logic equivalence
- Build passes with zero TypeScript errors (bun run build ✅)
- LSP diagnostics clean on all modified files
