Fetch is the only git command Codeman runs that writes, and the only one that runs a
repository's own fetch-post hook, so it stays behind a click and off by default. The Git
status window's header row gains Fetch; App Settings -> Bottom bar gains the switch and
the interval, synced because the scheduler acts on them, and Session Options -> Git
overrides both per case. The scheduler reads settings fresh each tick, times the interval
from the start of a run, never overlaps runs, and re-checks the Docker and remote rules
every tick before any git runs. Nothing but remote-tracking refs moves: HEAD, the index
and the working tree are proven unchanged against real git while origin/main advances.
Tests: src/git-fetch.ts and the scheduler, the per-case settings route, the synced/display
setting split, the two new i18n rows, and the Fetch block of the Git status browser suite.
restoreMuxSessions() re-applied name, auto-clear, auto-compact, auto-resume, nice and the
flicker filter from state.json but not color, pinned/pinnedAt or imageWatcherEnabled, which
the reboot-restore path (reapplyPersistedSessionState) already restores. After a restart or
crash a surviving pane came back uncoloured, unpinned and with its image watcher off, and the
next persist wrote that over the saved values. Found by killing -9 a server with a coloured,
pinned shell session and restarting it.
