Address rewinds/edits via SQLite messages.id (truncate_before_row_id)
instead of shifting user ordinals. Resolve against in-memory stamps,
then durable session history when live turns drop _row_id; refuse
unknown durable targets with 4018 (no ordinal fallback) and 4030 on
ordinal/row_id mismatch. Stamp _row_id on insert, load row ids on
resume paths, send rowId from Desktop, filter renderer-synthetic ids,
and stop silently resending failed targeted edits without truncation.
Add production-shaped SessionDB tests for resolve and fail-closed paths.
