Update @github/copilot to 1.0.21

[github-actions]

Automated bump of @github/copilot to 1.0.21. The codegen renamed session.compaction.compact → session.history.compact and added new session.history.truncate and sessions.fork RPCs, requiring updates across tests and docs.

Generated code

• Updated @github/copilot in nodejs/package.json and test/harness/package.json
• Re-ran codegen for all 4 SDKs (Node.js, Python, Go, .NET)

E2E test fixes

• Updated all references from compaction.compact() to history.compact() across Node.js, Python, Go, and .NET E2E tests

Documentation

• Updated docs/troubleshooting/compatibility.md to reflect the rename and added missing entries for session.history.truncate and sessions.fork

- const result = await session.rpc.compaction.compact();
+ const result = await session.rpc.history.compact();

@copilot is there any documentation or tests or anything that needs to be updated in reaction to these changes? Please ensure everything builds and all tests pass.

Yes — the generated code renamed session.compaction.compact to session.history.compact, which broke references in E2E tests and documentation. Fixed in ce6b64d:

• Updated E2E tests in all 4 SDKs (Node.js, Python, Go, .NET) to use history.compact() instead of compaction.compact()
• Updated docs/troubleshooting/compatibility.md to reflect the new API path

Builds pass for all SDKs. Unit tests pass: Node.js (205 passed, 3 pre-existing vision timeout flakes), Python (87 passed), Go (all passed), .NET (all passed). Go E2E tests also compile successfully with the updated API.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Cross-SDK Consistency Review ✅

This PR maintains excellent feature parity and consistency across all four SDK implementations. Here's a summary of the changes and their cross-SDK coverage:

Changes Reviewed

Change	Node.js	Python	Go	.NET
session.compaction.compact → session.history.compact	✅ session.rpc.history.compact()	✅ session.rpc.history.compact()	✅ session.RPC.History.Compact()	✅ session.Rpc.History.CompactAsync()
New session.history.truncate	✅ session.rpc.history.truncate(params)	✅ session.rpc.history.truncate(params)	✅ session.RPC.History.Truncate(ctx, params)	✅ session.Rpc.History.TruncateAsync(eventId)
New sessions.fork (server-level)	✅ server.rpc.sessions.fork(params)	✅ sessions_rpc.fork(params)	✅ ServerSessionsApi.Fork(ctx, params)	✅ ServerRpc.ForkAsync(sessionId, ...)

Observations

• API placement is consistent: sessions.fork is correctly scoped as a server-level RPC in all SDKs, while history.compact and history.truncate remain session-scoped.
• Naming conventions respected: camelCase (Node.js), snake_case (Python), PascalCase (Go/exported, .NET).
• E2E tests updated in all four SDKs for the compact rename.
• Documentation updated in docs/troubleshooting/compatibility.md to reflect the rename and the two new RPCs.

No inconsistencies found. 🎉
