Upstream sync: GitHubToken rename, sendAndWait cancellation fix, Foundry Local docs

[Copilot]

Ports 6 upstream commits from github/copilot-sdk (c4b3b36→f0909a7).

Changes ported

GithubToken → GitHubToken rename (99c7c52)

• New canonical methods: getGitHubToken() / setGitHubToken() on CopilotClientOptions
• Old getGithubToken() / setGithubToken() retained as @Deprecated for backward compatibility
• Error message updated: "GithubToken and UseLoggedInUser cannot be used..." → "GitHubToken..."

// New (preferred)
new CopilotClientOptions().setGitHubToken("gho_...");

// Old (still works, but deprecated)
new CopilotClientOptions().setGithubToken("gho_...");

sendAndWait cancellation fix (f0909a7)
Previously, calling cancel(true) on the returned CompletableFuture left the event subscription and timeout scheduler running (resource leak). Refactored to use an explicit result future: when cancelled externally, the inner future is cancelled too, triggering proper cleanup.

Microsoft Foundry Local docs (0e6561d)
Added Foundry Local to the BYOK provider table in advanced.md with setup instructions (dynamic port behavior, foundry model run, foundry service status).

Not ported

• 5a9b475 — Node.js dependency bump, not applicable
• eaf06cd — Node.js docs validation script fix, not applicable
• dea514d — .exe download timeout fix (NuGet packaging), Java SDK does not bundle CLI

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:

• checkstyle.org
  • Triggering command: /opt/hostedtoolcache/CodeQL/2.24.0/x64/codeql/tools/linux64/java/bin/java /opt/hostedtoolcache/CodeQL/2.24.0/x64/codeql/tools/linux64/java/bin/java -jar /opt/hostedtoolcache/CodeQL/2.24.0/x64/codeql/xml/tools/xml-extractor.jar --fileList=/home/REDACTED/work/copilot-sdk-java/.codeql-scratch/dbs/java/working/files-to-index2919233545206330813.list --sourceArchiveDir=/home/REDACTED/work/copilot-sdk-java/.codeql-scratch/dbs/java/src --outputDir=/home/REDACTED/work/copilot-sdk-java/.codeql-scratch/dbs/java/trap/java /@github/copilot-linux-x64/copilot ndor/bin/which (dns block)

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)
