Desktop status bar

A 24 px strip at the bottom of the window with the always-on document state. Single source of truth for things that the title bar shouldn't have to carry.

Cells

Cell	Content	Interaction
Repo (left)	GitHub icon + <owner/name> · <branch> ↑↓± (or "No repo" / "No remote")	Click → connect or sync; right-click → context menu
Cursor (right cluster)	L<n>:C<n> while focus is in the editor	Read-only
Words	Live word count of the current buffer	Read-only
Save state	● green = clean, amber = unsaved	Hover for tooltip

The mode toggle (View / Split / Edit) stays in the title bar as the segmented pill from #115 — keeping it close to the filename made it the more reachable affordance, and a status bar duplicate would create two truths.

Behavior

• Word count updates on every editor input event (split + edit modes).
• Cursor appears only while a textarea has focus; hidden on view mode and on blur.
• Save state flips to is-dirty (amber) on first edit; back to clean on save.
• Repo click is contextual:
  • When unconnected → opens the connect modal.
  • When connected → triggers sync (commit + pull-rebase + push).
• Repo right-click reveals the full menu: Sync / Connect to a different repo.

Why a status bar at the bottom

Modern markdown apps split running state into two zones: a tight title bar at the top (file + mode) and an unobtrusive status bar at the bottom (instrumentation). It keeps the chrome out of the reading column and gives the user a single place to glance at "what's happening?" — including dirty state, which used to live nowhere visible.

Files

• apps/electron/renderer/index.html — <footer class="mid-statusbar"> shell. Sidebar repo bar removed.
• apps/electron/renderer/renderer.ts — refreshRepoStatus (rewritten for the new DOM), updateWordCount, updateSaveIndicator, updateCursor, hideCursor. Wired into loadFileContent, saveFile, setMode, and the textarea input/keyup/click/focus/blur events.
• apps/electron/renderer/renderer.css — .mid-statusbar, .mid-status-cell*, .mid-status-dot, .mid-status-spacer. Body grid changed from 2 rows → 3 rows.

Verifying

1. Launch — status bar shows "No repo · 0 words · ● (saved)".
2. Open a folder of a connected repo — repo cell shows <owner/name> · main.
3. Open a file → words count updates; save dot stays green.
4. Switch to Edit / Split mode — cursor cell appears, tracks line/column as you type.
5. Edit a character — save dot flips amber.
6. Cmd+S — save dot flips back to green; word count re-flashes if changed.
7. Click the repo cell when connected — runs sync; status updates with new ahead/behind/dirty.
8. Right-click the repo cell — menu offers Sync / Connect to a different repo.
