_migrate_to_v3 deduplicated duplicate archive_id rows with a bare-column
GROUP BY, which lets SQLite keep an arbitrary row per group (in practice the
older row, dropping the latest), and copied rows with SELECT *, which relies
on positional column matching between the v2 and v3 schemas.
- Keep MAX(id) per archive_id group ("latest insert wins") instead of
GROUP BY's implementation-defined pick.
- Sweep replaces_db_id / replaced_by_db_id after dedupe, NULLing references
to dropped rows so the migrated table carries no dangling XEP-0308 (LMC)
links (the "Broken LMC reference" condition verify_integrity flags).
- List columns explicitly instead of SELECT * so the copy cannot mis-bind,
and note at the schema that column changes must be mirrored here.
