Add E2E test for session.providerEndpoint.get

[SteveSandersonMS]

Adds a Node E2E test for the new session.providerEndpoint.get shared API (not yet shipped).

The new RPC returns the provider endpoint + credentials for a session — the BYOK config if one is set, otherwise the resolved CAPI endpoint — so SDK consumers can call the LLM backend directly with their own OpenAI/Anthropic client.

Changes

• Regenerated nodejs/src/generated/rpc.ts and session-events.ts against the runtime schema that adds providerEndpoint.
• New nodejs/test/e2e/provider_endpoint.e2e.test.ts covering:
  • BYOK: returns protocol, baseUrl, apiKey, headers from the configured provider.
  • CAPI: returns the resolved CAPI base URL (using the harness CapiProxy so no real network calls).

Validating

Built the runtime branch locally and pointed the harness at it:

COPILOT_CLI_PATH=<runtime>\dist-cli\index.js npm run test:e2e -- provider_endpoint

Both tests pass.

Draft because this depends on the runtime PR landing + a release that includes the new schema before it can run in CI.

Cross-SDK Consistency Review

This PR regenerates Node.js generated types against an updated runtime schema and adds E2E tests for session.providerEndpoint.get. Since this is a draft waiting on the runtime to ship, the following is a heads-up on what will be needed for full cross-SDK parity when this gets promoted.

New APIs added (Node.js only)

The regenerated rpc.ts introduces several new items that will need to be propagated to all other SDK generated files via the codegen scripts (scripts/codegen/{go,csharp,python,rust}.ts and the Java codegen):

New addition	Node.js location	Other SDKs status
ProviderEndpoint interface	rpc.ts	❌ Not yet in Go/Python/.NET/Rust/Java
ProviderSessionToken interface	rpc.ts	❌ Not yet in other SDKs
ProviderWireProtocol enum	rpc.ts	❌ Not yet in other SDKs
ProviderEndpointGetRequest	rpc.ts	❌ Not yet in other SDKs
session.rpc.providerEndpoint.get()	createSessionRpc	❌ Not yet in other SDKs
agents.discover	createServerRpc	❌ Not yet in Go/Python/.NET/Rust/Java
ServerAgentList, ServerInstructionSourceList	rpc.ts	❌ Not yet in other SDKs
createInternalSessionRpc	rpc.ts	SDK-internal, may not apply

Schema field changes that also need propagation

The following field-level schema changes in Node.js generated types will also need to be reflected in the other SDKs' generated files:

• ScheduleEntry: intervalMs changed from required → optional; added cron, tz, at fields
• TaskAgentInfo: added resolvedModel field
• ResumeData (session-events.ts): added eventsFileSizeBytes
• ScheduleCreatedData (session-events.ts): added at, cron, tz fields

E2E tests to add

Once the runtime ships, session.providerEndpoint.get tests analogous to nodejs/test/e2e/provider_endpoint.e2e.test.ts should be added for:

• Python (python/e2e/)
• Go (go/ — look at existing *_test.go E2E patterns)
• .NET (dotnet/test/)
• Rust (rust/tests/e2e/)
• Java (java/src/test/java/**/e2e/)

No action needed now

Since this is a draft waiting on the runtime release, the above is expected to be incomplete at this stage. When the runtime PR lands and this is undrafted, running just codegen (or the per-language codegen commands) against the updated schema should regenerate the other SDKs' files automatically — the main gap to track is adding the per-language E2E tests.

The Node.js test implementation looks correct and comprehensive (covers both BYOK and CAPI-OAuth cases). 👍
