This PR optimizes the POST /marketplace/publish endpoint by offloading blocking synchronous I/O operations (bundle inspection and network upload) to a thread pool. This prevents the FastAPI event loop from being blocked during long-running publish operations.

Additionally, it fixes a critical bug in the endpoint where Bundle.from_file was called, but the method does not exist on the Bundle class. This was replaced with inspect_bundle from skillmeat.core.sharing.builder.

Note: Similar issues exist in install_listing endpoint but were left out of scope for this performance optimization task as requested by review.

Performance Impact:

  • Baseline: Concurrent requests blocked during publish (approx 2s delay).
  • Improved: Concurrent requests processed immediately (approx 0.012s latency).

- Replaced blocking synchronous calls with `run_in_threadpool` wrapper.
- Replaced usage of non-existent `Bundle.from_file` method with `inspect_bundle` in `publish_bundle`.
- Verified performance improvement with a reproduction script showing reduced latency for concurrent requests.
