dimitar 3d389ac3e8 feat: M3 — TUI interaction (periodic scan, countdown, change markers)
Replace the static-scan boot in the TUI with a reactive scan loop anchored
on bubbletea.Tick and user-driven 'r' rescan.

Scan loop (tea.Tick instead of goroutine — no leak):
- Init returns a tick Cmd when --interval > 0; on each tick the model
  fires scanCmd and chains the next tick in the Update handler, producing
  a self-regulating interval loop that stops naturally on quit
- 'r' key triggers an immediate rescan when the model is not already
  loading, for on-demand refresh
- scanResultMsg handler records prevResult, computes status.Changed into a
  changed set (keyed by repo path), and updates lastScan
- scanErrorMsg stores the error text on the model (displayed in the status
  bar) without stopping the loop

Change detection in the view:
- Repos whose state changed since the previous scan get a ▲ prefix (yellow
  bold) in the repo list, distinguishing them from the > cursor

Status bar improvements:
- Countdown "next: 23s" when --interval is active, computed from
  time.Since(lastScan); "scanning…" shown during async scans
- Updated keybinding hints: r refresh, g/G home/end

Navigation additions:
- g/Home jumps to top, G/End jumps to bottom

Styles:
- Changed style (yellow bold foreground) for ▲ markers
- Styles struct now includes all five variants

Tests:
- Home/End keys navigate to first/last repo
- 'r' fires scanCmd when not loading
- ▲ marker appears for changed repos
- Interval tick fires scan when idle
- Countdown "next:" shown in status bar

Verified: go build, go vet, go test -race (12 packages), gofmt clean.
