gsxdsm d306ab67b2 FN-8140: reuse host TaskStore across extension loads

Reuse process-wide extension store state to prevent duplicate backend boots from blocking agent reads.

- Share TaskStore cache, boot-inflight, and failure cooldown state across ESM module instances.
- Preserve host-injected stores when cold boots race and add bounded boot-resolution coverage.
- Add a patch changeset for responsive agent reads.
