15 vitest specs total:
- 9 lifted from authd's tests/db/migrate.test.ts. Specs that referenced
the on-disk migrations dir now write fixtures into a per-test tmpdir
(package ships no migrations dir of its own).
- 3 new specs covering the genesisProbeTable parameter (default, custom
table name, opt-out via stampGenesis=false).
- 3 new specs covering runMigrateCli (migrate / status / stamp) using
PassThrough stream capture.
Extracts the union of authd's three CLI scripts (db-migrate.ts,
db-status.ts, db-stamp.ts) into one wrapper. Consumers wire a ~5-line shim
that injects their own openDb / migrationsDir / config-loading logic. The
wrapper returns an exit code rather than calling process.exit, which keeps
it testable via PassThrough stream capture.
Forward-only SQLite migration runner lifted from authd (src/db/migrate.ts,
PR #14 / merge ced21ab) and parameterized for cross-project use. The single
deliberate API change vs. authd's source: the previously-hardcoded
GENESIS_PROBE_TABLE = 'users' is now an ApplyOptions.genesisProbeTable?: string
option (default 'users').
