Update Copilot CLI to 1.0.86-1

[github-actions]

Automated update of the Copilot CLI release to version 1.0.86-1.

Changes

• Updated the shared release pin in nodejs/package.json
• Validated the release assets listed in SHA256SUMS.txt
• Re-ran all code generators (scripts/codegen)
• Formatted generated output
• Regenerated Java types from the pinned CLI release schemas

Java Handwritten Code Adaptation Plan

If java-sdk-tests CI fails on this PR, follow these steps:

1. Identify failures: Run mvn clean, mvn verify from java/ locally or check the java-sdk-tests workflow run logs.
2. Categorize errors:
   • Constructor signature changes (new fields added to generated records)
   • Enum value additions/renames in generated types
   • New event types requiring handler registration
   • Removed or renamed generated types
3. Fix handwritten source (java/sdk/src/main/java/com/github/copilot/sdk/):
   • Update call sites passing positional constructor args to include new fields (typically null for optional new fields).
   • Update switch/if-else over enum values to handle new cases.
   • Register handlers for new event types in CopilotSession.java if applicable.
4. Fix handwritten tests (java/sdk/src/test/java/com/github/copilot/sdk/):
   • Same constructor/enum fixes as above.
   • Add new test methods for new functionality if the change adds user-facing API surface.
5. Validate: cd java && mvn clean test-compile jar:jar && mvn verify -Dskip.test.harness=true
6. Format: cd java && mvn spotless:apply
7. Push fixes to this PR branch.

To automate this, trigger the java-adapt-handwritten-code-to-accept-upgrade-changes agentic workflow instead.

🔵 Needs a closer look

The generated Python field ordering and exhaustive public Rust structs introduce compatibility breaks.

Superseded by CLI 1.0.86-2 adoption. Preserving the separately reproduced pre-existing native SIGCHLD/SA_ONSTACK defect investigation; closing this version bump does not resolve that defect.
