Add MCP OAuth lifecycle SDK support (#1669)

Expose host-delegated MCP OAuth handling across SDK languages, sync generated RPC and event models to the lifecycle contract, and add cross-language E2E coverage for initial auth, refresh, upscope, reauth, and cancellation.

Add GitHub-anchored attachment variants to Attachment enum (#1823)

* Add GitHub-anchored attachment variants to Attachment enum

Add the nine GitHub-anchored attachment variants (github_commit,
github_release, github_actions_job, github_repository, github_file_diff,
github_tree_comparison, github_url, github_file, github_snippet) to the
hand-written `Attachment` enum so copilotd no longer drops them when
(de)serializing at the SDK boundary.

The fields are inlined directly into each variant, mirroring the existing
github_reference variant, rather than wrapping the generated
`AttachmentGitHub*` structs. Wrapping would emit a duplicate `type` JSON
key (the generated structs embed their own discriminator) and break the
enum's `Eq` derive (the generated structs do not derive Eq). Nested
object fields use local sub-structs that derive Eq.

* Make attachment match arms explicit and harden duplicate-type test

List github_reference + the 9 GitHub-anchored variants explicitly in the
display-name match arms instead of a wildcard, so future Attachment variants
trigger a compile error and force an explicit display-behavior decision.

Count raw "type": occurrences in the serialized string rather than keys on a
parsed Value (which silently dedupes), so the test can actually catch a
duplicate-type regression.

Add getBearerToken callback for BYOK providers (Managed Identity) (#1748

)

Lets BYOK provider configs supply a getBearerToken callback so the SDK
consumer resolves bearer tokens (e.g. Azure Managed Identity) on demand.
The callback never crosses the wire: the SDK strips it from the provider
config, sends a `hasBearerTokenProvider: true` flag, and answers the
runtime's session-scoped `providerToken.getToken` RPC by routing to the
matching per-provider callback. The returned token is applied as the
Authorization header for outbound model requests; the consumer owns
caching/refresh.

Implemented across all SDKs (Node, .NET, Go, Java, Python, Rust) with
e2e tests. The generated RPC files are intentionally left as the
committed CLI 1.0.65 codegen output (providerToken.getToken +
hasBearerTokenProvider) rather than hand-edited.
