fix: resolve React hooks/compiler ESLint errors

- Wrap ref assignments in useEffect to fix refs-during-render in
  useTabManagement, useKeyboardNavigation, and Editor
- Rewrite useAppKeyboard to define keyMap inside useEffect, eliminating
  ref access during render
- Add eslint-disable for react-hooks/set-state-in-effect on legitimate
  dialog reset patterns (CommitDialog, CreateNoteDialog, CreateTypeDialog,
  QuickOpenPalette, AIChatPanel, useVaultLoader)
- Add eslint-disable for react-hooks/static-components on icon lookups
  (NoteItem, NoteList PinnedCard) — stateless icon components from a
  static map
- Add eslint-disable for react-hooks/purity on Date.now() in
  NoteItem TrashDateLine — intentionally memoized on trashedAt
- Remove unused `model` param from buildSystemPrompt (ai-chat.ts) and
  update callers
- Fix exhaustive-deps: suppress vault object dep in App.tsx git history
  effect (vault object is unstable, loadGitHistory is the real dep)
- Remove unused `modifiedFiles` from useNoteListData params and caller
- Add missing `ref` to Sidebar useOutsideClick deps
