fix(GFG-D2): muse+git-mirror D2 uses muse_commit_id ID space

Compare last_export.muse_commit_id to Muse tip for D2; keep git_sha for realign from_ref/ancestry only. Stops healthy bridges looking permanently drifted under Muse 0.2.x content-hash tips. Freeze pass D2F-r2; BV pass D2F-BV-r1; §D2F.9 tests green.
