v0.2.85

- Add OPFS synchronous access handles and committed cache records, and update the bundled TVM web runtime to `0.27.0-dev0`.
- Return OpenAI-compatible `created` timestamps in seconds.
- Register service-worker handlers during startup so restarted workers can receive requests.
- Preserve recovered worker model state to avoid repeated reloads.
- Prevent hangs when initializing invalid structural-tag constraints.

- Render example output safely and correct cached-model `appConfig` examples.

This update continues to use the existing `v0_2_84/base` model libraries. No new model binaries are required by the validated paths.
