mm_retrieve_prior_work

Regenerate prior-work.md for an existing spec by re-running similarity retrieval against the current spec index at .mm/index/specs.json. Idempotent — running twice on the same inputs produces a byte-identical file (the generated_at timestamp is preserved when the body is unchanged). When no completed specs match above the configured similarity_threshold, writes the empty-state file with a clear empty_reason.
