garrytan eb44a747a9 test(shard-engine): engine unit tests, fixture-corpus equivalence, per-lane CLI parity
- test/shard-engine.test.ts: failing/unhandled/module-load output fails both
  lanes, per-lane zero-execution and seed rules, whole-group kill on a wall
  timeout (both lanes), mocked-win32 path with no negative-pid kill,
  companion settle order, log capture, sandbox isolation, flag loop.
- test/shard-engine-equivalence.test.ts + test/fixtures/shard-equivalence:
  seven outcome fixtures plus one real shard, run through both lanes and
  compared with classifications recorded from the base runners (96764e80).
- test/shard-cli-parity.test.ts + test/fixtures/shard-cli-parity: flag set,
  defaults, validation errors and the Unknown argument error per lane match
  the base runners.

* the same `Unknown argument:` error, as the pre-engine runners recorded in
