docs(runs): teach an agent to read a run's results and its trace

Overview of Changes

An agent that must report on a run calls qawolf run get. The response links a Playwright trace, a video and the logs, but nothing tells the agent how to use them. The usual advice for a trace is npx playwright show-trace, which opens a browser and gives a shell no result. The response also hides some of its own shape: a run where every flow passed has no failure object, so the diagnosis fields are invisible until a flow fails.

This adds a skill reference for reading a run's results. The prose is hand written. The field list is generated from the run.get contract, so it cannot become different from the installed version.

• skills/qawolf-cli/references/run-results.md: the new reference. It gives the response shape, the fields that a passing run does not show, the four rules for the artifact URLs (they expire, they can give a 404, a plain GET is sufficient, and the returned runId is the canonical one), and a section on the trace. A trace is a zip of newline-delimited JSON. The section gives the event types, the two traps (times are milliseconds, and values use a serialized envelope), and a script that pairs each call with its result to print an action timeline with the failures.
• src/commands/qawolfCliRunResults.template.md: the source of that file. The generated field list goes between the fields:start and fields:end markers.
• src/commands/skillRunResults.ts: renders one bullet for each documented field of a contract, and splices the result into the template. It throws if the contract documents no field, because an empty reference is worse than a build failure.
• src/core/publicApi/outputFields.ts: converts a contract output schema to a flat list of paths and descriptions. [] marks an array, so flows[].attempts[].traceUrl is the trace URL of one attempt of one flow. A field that the response shapes pin to different literals shows the values it takes, for example One of: passed, failed, canceled, because one branch's prose describes that branch and not the field.
• scripts/genSkillMd.ts: generates the new file next to SKILL.md. Both run in bun run generate.
• src/commands/qawolfCliSkill.template.md: tells the agent to read the new reference before it reports on a run or opens a trace.

Command help and command registration do not change. The new modules are used only by the generation script, so they are not in dist/cli.js.

Testing

bun run test
bun run typecheck
bun run lint
bun run format:check
bun run knip

• 12 new tests across outputFields.test.ts / skillRunResults.test.ts: nested array paths, one entry for a field that more than one union branch holds, the values of a literal field, fields without a description left out, a date kept with its description, the rendered bullets, the error when a contract documents nothing, the splice, and the check that the generated file agrees with the template and the contract.

Walkthrough

Adds contract-driven response-field documentation for qawolf run get. The generator injects these fields into a run-results reference. The reference documents run status, attempts, artifacts, signed URLs, Playwright traces, timestamps, serialized values, and failure diagnosis. The CLI skill directs readers to inspect JSON output and consult the reference before interpreting results or opening traces. Tests cover schema traversal, rendering, marker validation, and generated-reference synchronization.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 6c3cd

This PR adds generated guidance for reading run results and traces without changing command behavior or runtime functionality; no actionable merge-blocking risk remains after normal checks and review.

Inline comments:
In `@src/commands/qawolfCliRunResults.template.md`:
- Around line 66-73: Update the archive description in the qawolf CLI run
results guidance to state that trace.zip is a ZIP archive containing
newline-delimited JSON files, including trace.trace and trace.network, rather
than describing the archive itself as newline-delimited JSON.
- Around line 15-23: Add the text language tag to the opening fences for both
fenced text blocks in the reference, including the blocks around the run/flows
structure and the corresponding section near the second occurrence, so the
generated documentation satisfies MD040.

In `@src/core/publicApi/outputFields.ts`:
- Around line 55-58: Update the branches handling in collect so literal union
branches are recorded at the current path before recursive traversal, preserving
existing behavior for non-literal branches. Add a regression test covering
buildOutputFieldDocs with a direct union of string literals and verifying the
field and its literal values are included.
