feat: support task outcome reports in browser agent

[artiom]

Summary

• Accept typed reportOutcome commands on both browser-agent surfaces, with a boolean verdict and optional fixed reason category.
• Forward reports without replacing the last page-facing result. Preserve command options when reports precede a screenshot or another page command.

Test plan

• npm test passes locally: 907 tests.
• npm run lint passes locally.
• Full and compliant WebSocket tests verify forwarding and returned page results; schema tests reject malformed verdicts.
• Top-level verdict tests reject malformed input before opening a connection and forward a valid false verdict.
• A screenshot-to-disk regression failed before the command/result pairing fix and passes afterward.
• Coverage thresholds and a hosted-service smoke test were not run.

Assumptions made

src/tools/agent.ts omits reporting commands from the user-facing result array, so an index into the original command array cannot reliably recover the final page command's options. Keeping params beside each result preserves the existing formatting contract. Reverting this local change would reintroduce the tested screenshot regression.

Checklist

• Commits use conventional-commit prefixes.
• No dependencies added.
• Command schema descriptions document the boolean and optional reason contract.

Walkthrough

The agent now accepts and validates reportOutcome commands in both compliance modes. It excludes outcome and close responses from the final user-facing result. Batch handling preserves command parameters, including screenshot toDisk.

Changes

Outcome reporting

Layer / File(s)	Summary
Outcome command contract src/tools/schemas.ts, test/tools/schemas.spec.ts, test/tools/compliance-mode.spec.ts	Adds the reportOutcome schema with a required boolean success field and supported completion reasons. Registers and tests it in full and compliant command lists.
Single-command outcome validation src/tools/agent.ts, test/tools/agent.spec.ts	Validates top-level reportOutcome calls and rejects malformed verdicts before forwarding.
Batch result handling src/tools/agent.ts, test/tools/agent.spec.ts	Retains command parameters and full command data. Handles close and outcome-report commands as non-user-facing results. Preserves screenshot options and returns the subsequent page result.

Review monitoring complete for the current head. Fixed top-level reportOutcome validation; malformed verdicts are rejected before a browser connection, and valid false verdicts still forward. Retained intentional best-effort delivery so reporting failures do not replace page results or block close. Local build, 907 tests, lint and formatting passed. All 5 current checks passed; no unresolved review threads or merge conflicts remain. Current-head CodeRabbit status passed; no new-head bot review submission was observed. Ready for human review.
