feat(desktop): information architecture overhaul — home, records, meetings first

Wave 2 of the 2026-09-28 design overhaul ("records are the main
character, a quiet instrument"). Decisions: design.md.

- Shell: sidebar with primary Home / Records / Meetings (Ctrl+1..3) and a
  secondary "Tools" group; every item is a button with aria-current.
  The status bar is removed — its "100% LOCAL PRIVACY · ZERO CLOUD SYNC"
  claim contradicted device sync; the sidebar shows only queried state.
- Navigation context (routes, params, back, useRouteRequest) so Home can
  open a specific meeting or record.
- Home replaces the dashboard: dictation key, start actions, only real
  problems, one-line summary, recent records and meetings, file
  transcription, free-tier limits.
- Settings become a full-screen route with vertical tabs (tabs no longer
  clip) and a shared row grammar; long-standing bugs fixed: team and
  enterprise tiers crashed the license tab (currentTier undefined),
  first-run onboarding could not be left, Pro+ saw "upgrade to Pro+".
- Records: date-grouped single list with in-place expansion, search and
  tags together, mode/favorite filters, load more past 50, undoable
  delete. Meetings: list with search/rename/delete, summary-first detail
  (summary | transcript | documents | my notes), notes persisted locally
  instead of being lost. Tools pages cleaned up; stale-closure example
  chips and a 1550x mouse-distance bug fixed.
- Shared pieces: PageHeader, EmptyStateCard, SearchInput ("/" works),
  ConfirmDialog, notify with undo; display-labels maps domain values to
  typed i18n keys so missing keys fail to compile.
- Mono font stack falls back to Pretendard for Hangul (Korean labels no
  longer render spaced out).
- i18n: new ko/en keys via scripts/i18n-add-keys.mjs (one read-merge-
  write so parallel editors cannot clobber locale files).

Some renderer files also carried pre-existing in-flight changes (error
recovery deep links, meeting document hooks); they are included as-is.
