Remove legacy React/Ink TUI and fix TypeScript errors

- Delete old tui/ React/Ink implementation (App.tsx, components/, hooks/, store.ts)
  - Migrate to tui-solid/ as the sole TUI implementation
  - Update tui/index.ts to re-export from tui-solid and @/types/tui

  TypeScript fixes:
  - Add missing PreCompact to hook event constants
  - Fix path aliases (@src/ -> @/, @constants/)
  - Remove unused imports across service files
  - Add explicit type annotations to callback parameters
  - Replace Bun.file/write with Node.js fs/promises in mcp/registry
  - Fix Map.some() -> Array.from().some() in registry
  - Fix addServer() call signature
  - Add missing description to brain-mcp schema items
  - Fix typo in progress-bar import (@interfactes -> @interfaces)
