/**
 * `os migrate meta` — end-to-end over the REAL CLI process (ADR-0087 D3/D5).
 *
 * The chain's transforms are fixture-tested in @objectstack/spec
 * (conversions.test.ts, migrations.test.ts), but the COMMAND path — config
 * loading via bundleRequire, the convert:false normalization that keeps the
 * chain attributable, the schema-validity verdict, the machine JSON shape,
 * `--out` snapshots, and the support-floor refusal — had no test at all.
 * This spawns `bin/run-dev.js` against a temp project authored in the
 * PRE-protocol-17 dialect, exercising one key from every v17 conversion
 * family in a single pass, exactly the cross-major "consumer upgrades"
 * scenario the command exists for.
