Merge main into feature branch and recompile generated/setup artifacts

[Copilot]

This PR brings the branch up to date with main and refreshes compiled/generated outputs so the branch reflects current upstream behavior and docs. It resolves drift introduced since the branch diverged.

• Branch sync

  • Merged latest origin/main into copilot/update-forecast-command using a standard merge commit.
  • Pulled in upstream updates to the setup JS driver and related failure-handling paths.

• Recompiled outputs

  • Re-ran repository recompile flow so built/generated artifacts are aligned with merged source.
  • Updated tracked outputs produced by the normal build/recompile pipeline (no bespoke generation path).

• Upstream file updates now included

  • actions/setup/js/copilot_sdk_driver.cjs
  • actions/setup/js/copilot_sdk_driver.test.cjs
  • actions/setup/js/handle_agent_failure.cjs
  • actions/setup/js/handle_agent_failure.test.cjs
  • docs/src/content/docs/specs/copilot-sdk-driver-specification.md

Pull request overview

This PR syncs the feature branch with main and refreshes generated/setup artifacts, resulting in updated maintenance workflow behavior for the forecast operation (narrower log warm-up artifact scope and a longer forecast compute timeout).

Changes:

• Update forecast maintenance job to warm the logs cache using only the agent artifact set (gh aw logs --artifacts agent).
• Increase the forecast command’s graceful computation timeout from 10 to 30 minutes (and update the corresponding timeout messaging).
• Align generator code, generated workflow YAML, tests, and docs to the new forecast behavior.
