Phase 10 HTTP engine docs, harness, and baseline

[nova-rey]

Summary

• capture seeded HTTP engine baseline artifacts and refresh snapshot/entrypoint metadata

Testing

Import helper that does not exist

The parity harness test imports build_inprocess_engine_adapter, but crapssim_control.engine.factory exposes only build_engine_adapter; no such function exists anywhere in the repo. In environments where crapssim_api.http and fastapi are installed (so the module is not skipped), the import fails before the test body executes, leaving the new test suite permanently broken. Please import the correct builder or implement the missing helper so the test can actually run.
