feat(lifecycle): auto-commit sweep of the machine flake before pull/rebuild/home
With settings.autoCommit on, only menu/theme mutations were committed
(theme-sync pathspec-limits to theme-state.json by design), so hand
edits to system.nix/home.nix and lock bumps stayed forever-dirty.

New internal nomarchy-autocommit (nomarchy-lifecycle): live-reads the
same flag, commits everything dirty as "nomarchy: auto-commit before
<pull|rebuild|home switch>" with the swept file list in the body,
fallback identity, never fatal (|| true at call sites). Called at the
top of all three lifecycle commands; before the ff-only pull it also
un-dirties the tree. Exposed via passthru.autocommit + package export;
guarded by checks.lifecycle-autocommit (sandbox repos: sweep, no-op on
clean/off/non-repo). Sync sweep: README, RECOVERY, ROADMAP, rofi
toggle, control-center prompt, theme-sync docstring, JOURNAL.

Verified: V1+ — flake check --no-build green; the new check builds;
end-to-end run of the built nomarchy-rebuild (stubbed sudo/rebuild)
against a copy of a real dirty ~/.nomarchy: 4 files → one commit,
clean tree. No VM boot — no session-visible surface.

# Opt-in sweep (settings.autoCommit — the same flag theme-sync honours):
# commit EVERYTHING dirty in the machine flake before a pull/rebuild/
# home switch, so hand edits to system.nix/home.nix and lock bumps land
# in history at the moment they become live — `git log` mirrors the
# generation list. Complements nomarchy-theme-sync's auto_commit, which
# is pathspec-limited to theme-state.json on menu writes precisely so
# half-finished hand edits never ride a settings-named commit; here the
# sweep is the point, and the commit body lists what was swept. Never
# fatal — callers `|| true` so a git hiccup can't block a rebuild. Not
# in the symlinkJoin paths (internal; callers use the store path) but
# exposed as passthru.autocommit for checks.lifecycle-autocommit.
