# ── memsearch memory git sync (fail-safe) ───────────────────────────────────
# Auto-commit + push the memsearch memory store (~/.memsearch) on session end.
# We own this sync here so we never patch the marketplace memsearch plugin
# (which clobbers on update). The whitelist .gitignore in ~/.memsearch tracks
# only memory/*.md + .gitignore, so `add -A` is safe.
#
# Robustness contract: this block MUST NEVER fail session shutdown.
# - Skips silently if ~/.memsearch is not a git repo.
# - Only commits when something is staged (no empty commits).
# - Push is hard-timeboxed and failures are swallowed; the next session's
# hook catches up since the daily memory files are append-only.
# Wrapped in a subshell with `|| true` so nothing here can abort the hook.
