Fix telemetry forwarding handshake CI failures

[stephentoub]

Summary

• Send the GitHub telemetry forwarding opt-in during the connection handshake across SDKs.
• Keep generated RPC files aligned by moving the extra handshake field into SDK-owned payload types.
• Update Go, .NET, and Rust tests for optional telemetry session ID / allow-all schema fields.

Validation

• cd nodejs && npm test -- client.test.ts
• cd python && python -m pytest test_client.py
• cd go && go test . ./rpc ./internal/e2e -run TestDoesNotExist
• cd dotnet && dotnet test test\GitHub.Copilot.SDK.Test.csproj --no-restore --filter "FullyQualifiedName~GitHubTelemetry" -m:1
• cd rust && cargo test --all-features github_telemetry

Not run locally: Java Maven validation (mvn is not available in this environment).

Pull request overview

This PR updates the cross-SDK connection handshake so that GitHub telemetry forwarding opt-in is sent during connect when a telemetry handler/callback is registered, preventing handshake-related CI failures and aligning behavior across languages.

Changes:

• Add enableGitHubTelemetryForwarding=true to the connect handshake across Node.js, Python, Go, .NET, Java, and Rust when a GitHub telemetry handler is provided (and omit it otherwise).
• Adjust SDK tests to cover the new handshake behavior and to tolerate optional sessionId / allow-all permission schema fields.
• In Rust, construct the connect payload locally (instead of using the generated request struct) to control the exact wire field name.

Cross-SDK Consistency Review ✅

This PR implements enableGitHubTelemetryForwarding in the connect handshake consistently across all six SDKs. Here's a quick summary:

SDK	Connect handshake flag	Unit tests	MCP OAuth status update
Node.js	✅	✅	✅
Python	✅	✅	✅
Go	✅	✅	✅
.NET	✅	✅	✅
Java	✅	✅	✅
Rust	✅	✅	✅

Notable observations

Rust gains stricter protocol version validation — Rust now returns InvalidProtocolVersion when the server reports a version outside u32 range, rather than silently succeeding with None. The other SDKs either silently truncate or may throw a language-level overflow exception. This is a correctness improvement, but if consistency of error-handling semantics matters, the other SDKs could benefit from a similar guard. Not blocking.

Java connect handshake uses HashMap instead of a typed struct — For session.create and session.resume, Java uses typed CreateSessionRequest/ResumeSessionRequest objects (with setEnableGitHubTelemetryForwarding()). For the new connect handshake, it uses an untyped HashMap<String, Object>. This is a reasonable pragmatic choice (the generated ConnectParams type didn't include the new field) and an internal implementation detail, but it's slightly inconsistent with the pattern used elsewhere in the Java SDK. Not blocking.

Overall the PR is well-structured and maintains feature parity across all SDKs.
