Summary by cubic

Adds A/B experiment support to the Daily News workflow and hardens reliability across the runtime and telemetry. Also improves CLI docs, safe-output tools, and version tracking.

• New Features

  • Daily News A/B test: prompt_style (detailed vs concise) with variant picker, artifact upload, and state pushed to experiments/dailynews.
  • Telemetry: emit synthetic OTLP exception events when runs time out or are cancelled without agent_output.json.
  • Safe outputs: new set-issue-field tool with optional allowed-fields, target, and repo targeting.
  • CLI docs: add gh aw lint and hidden gh aw experiments commands (list, analyze).
  • Version checker: track @playwright/cli (install, help discovery, release notes).

• Bug Fixes

  • Claude harness: avoid invalid --continue retries after SIGKILL/SIGTERM (137/143) or “no deferred tool marker”; strip user-supplied --continue; clearer retry logs; tests added.
  • Spinner: recover from Bubble Tea program panics and reliably reset running; tests added.
  • File copy: ensure close/sync correctness and remove partial destination on write errors; refactored copy helper with tests.
