feat(api): complete versioning coverage, OpenAPI docs sync, WebSocket…

[deborahamoni0-prog]

Completed Issues & Summary

1. Add versioning.rs coverage for the newly-completed handlers #859 Add versioning.rs coverage for the newly-completed handlers
   • Audited route registrations to ensure explicit /v1/... prefix attachment for all 13 handlers.
   • Added version negotiation middleware tests asserting that unversioned routes return 404 Not Found and unsupported versions
   return 406 Not Acceptable with structured error details.
   • Documented the current API version (1.0.0), supported versions, and deprecation policy in api-reference.md.
2. Add docs.rs-generated OpenAPI coverage for all wired endpoints #860 Add docs.rs-generated OpenAPI coverage for all wired endpoints
   • Configured main.rs:56-117 and schema definitions covering all wired endpoints.
   • Reconciled OpenAPI schemas with api-reference.md.
   • Added CI integration tests in integration_tests.rs:470-511 to fail if endpoint schemas or documentation drift.
3. Add websocket push for swap state changes #861 Add websocket push for swap state changes
   • Added subscribe_swap_status channel in websocket.rs:171-274 supporting both global and per-swap_id filtering.
   • Bridged contract events from events.rs (SwapInitiated, SwapAccepted, SwapCompleted) into WebSocket push notifications
   (swap_status_changed).
   • Added tests in websocket.rs:276-358 asserting timely delivery of pushed events to multiple subscribers within bounded time.
4. Add load-testing scenarios for the batch endpoints #862 Add load-testing scenarios for the batch endpoints
   • Added load-testing scenarios in load_testing.rs:212-323 for near max-size batch requests (batch_initiate_swap with 5, 25, and
   100 items).
   • Measured p50, p95, and p99 latencies, comparing single-item request overhead vs batch execution amortized throughput.
   • Documented load-testing benchmark findings in architecture.md.
