LORE 0.62.25 — Memory match errors

Memory match errors

• Fix memory replace|remove|move and filemap replace|remove reporting review_changed when --match hit no entry or several. They now return match_not_found or match_ambiguous and change nothing: the caller's match needs fixing, not a concurrent writer or stale review.
• Refuse a missing or empty --match, and a positional these commands do not take, as invalid_request. Previously memory replace "<old>" "<new>" joined both into the text and matched every entry; filemap remove <path> removed the only row of a one-row map.
• Report an unresolved or ambiguous project name (memory move --to, project move, backfill --project) the same way. review_changed remains for reviewed-snapshot, exact sync-replay and pending-listing changes.
