fix: handle run status, map failures to non-zero exit code, and expose metrics

[PunGrumpy]

Description

This pull request handles terminal statuses from @cursor/sdk and reports run outcomes accurately:

• Map cancelled and error run statuses from run.wait() to exit code 1.
• Capture error messages in stderr and surface them in step diagnostics and the job summary.
• Expose the new status output (finished, error, or cancelled).
• Add duration and total token usage to the GitHub Actions Job Summary table when provided by the SDK.
• Update runtime behavior, quickstart, troubleshooting, and generated reference documentation.

📝 Walkthrough

Walkthrough

The action now captures agent status, failure details, duration, and token usage. It exposes status as an output and includes available metadata in the job summary. Documentation and tests describe the updated behavior.

Changes

Agent run handling

Layer / File(s)	Summary
Run result handling src/types.ts, src/runner.ts, __tests__/runner.test.ts	runAgent awaits run.wait(), maps status and usage metadata, reports errors and cancellations, and returns exit code 1 for failed runs. Tests cover these states and metadata.

Output and summary wiring

Layer / File(s)	Summary
Output and summary wiring src/output.ts, action.yml, __tests__/output.test.ts	The action emits a status output. Job summaries conditionally include agent status, duration, and total tokens. Tests verify emitted outputs and table rows.

Documentation and release metadata

Layer / File(s)	Summary
Documentation and release metadata README.md, docs/content/*.mdx, .changeset/report-agent-status-and-failures.md	Documentation describes terminal statuses, exit codes, timeout and failure behavior, and available summary metadata. The changeset records a patch release.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to af584

This change improves failure reporting and adds status metadata, but timeout guidance can incorrectly promise a failed step when cancellation is unsupported, and the status-output coverage does not prove non-default status propagation. Correcting the documentation and strengthening the test would make the change ready to merge.

Poem

A rabbit checks the agent’s state,
And marks the finish, error, wait.
Tokens hop into the sum,
Duration joins the table drum.
Cancelled runs now speak up clear,
“One” hops out when trouble’s here.

Inline comments:
In `@__tests__/output.test.ts`:
- Line 136: Update the custom-status test to use a non-fallback status, such as
“cancelled” with exitCode 1, and assert that exact status in the result so
explicit status propagation is exercised.

In `@docs/content/troubleshooting.mdx`:
- Line 20: Correct the troubleshooting guidance to state that exit code 1
applies when the run reports cancelled, including timeout-triggered
cancellation; unsupported cancellation can finish with exit code 0. Update the
timeout explanation near the job summary without changing unrelated
documentation.
