feat: compact mode for short terminals and distraction-free toggle (#397)

## Summary
- Auto-hide TUI chrome (status line, table headers, scroll indicator,
help footer) when terminal height < 15 rows
- Add `D` keybinding to manually toggle distraction-free mode at any
terminal size
- Add `ROBOREV_SKIP_VERSION_CHECK=1` env var to skip daemon version
mismatch restarts (useful for `go run` development)
- Update mouse click handling to account for compact mode header offset

## Test plan
- [x] Existing tests updated and passing
- [x] New tests for compact mode rendering and distraction-free toggle
- [x] Manual: resize terminal below 15 rows, verify chrome is hidden
- [x] Manual: press `D` in queue view, verify chrome toggles
- [x] Manual: `ROBOREV_SKIP_VERSION_CHECK=1 go run ./cmd/roborev tui`
connects to running daemon

Closes #378
