Conformance matrix claims full support for missing source paths and unimplemented features

[nficano]

docs/conformance.md:11 through docs/conformance.md:38 marks many spec sections as fully implemented while pointing at paths that do not exist in this package, including arcp/runtime/auth.py, arcp/runtime/registry.py, arcp/runtime/resume.py, arcp/runtime/idempotency.py, arcp/runtime/context.py, arcp/runtime/delegation.py, arcp/runtime/capabilities.py, and arcp/runtime/job_store.py. The same table marks stream resume as full at docs/conformance.md:15, but tests/state/test_resume.py:48 explicitly skips the replay test because full resume replay is not implemented end-to-end. The notes at docs/conformance.md:44 also describe resume tokens on job.started and submit(resume_token=...), which does not match the current session-level SessionResume model or client API.

Fix prompt: Rebuild docs/conformance.md from the current implementation instead of the older package layout. Use real source paths under src/arcp, downgrade or mark incomplete any feature that is not implemented or not tested, and align the event names and resume mechanics with the actual message models. Add a CI check that every source path in the conformance table exists, and link each "Full" row to a passing conformance or state test so documentation status cannot outrun behavior.
