Improve pre-created pull request title and body

[Copilot]

The draft PR allocated by safe-outputs.create-pull-request.pre-create used the title [<workflow>] Work in progress, ignored the configured title-prefix, and had a one-line body that did not convey the PR's in-progress state or that steering the running agent is unsupported.

Title

• Starts with [WIP], then the configured title-prefix (applied via applyTitlePrefix, so spacing/duplication rules match other safe outputs), then text containing the workflow name.

[WIP] [bot] Daily Go Test Parallelizer: work in progress

Compiler

• addActivationPreCreatePullRequestStep emits GH_AW_PR_TITLE_PREFIX from create-pull-request.title-prefix; the env var is omitted when unset.

Body

• States the PR is a work in progress and currently contains no changes, links the workflow run, notes the title/body/commits are updated on completion and that changeless runs are closed automatically, and calls out that steering via comments or reviews is not supported yet.

Docs & tests

• Reference docs for pre-created pull requests describe the new title shape and body content.
• Go tests cover prefix propagation (set and unset); pre_create_pull_request.test.cjs covers the WIP marker, prefix placement, and body content. Workflow lock files recompiled.

Final resolution on current head 1b6b353c52:

• Title behavior: pre-created PR titles start with [WIP], then apply the configured title-prefix via applyTitlePrefix, followed by the workflow-specific work-in-progress text.
• Body behavior: the pre-created PR body now comes from actions/setup/md/pre_created_pull_request_body.md and is rendered with renderTemplateFromFile; it links the workflow run, states the PR is still in progress/no changes yet, explains completion/changeless-run behavior, and notes steering by PR comments/reviews is unsupported.
• Branch refresh: current branch includes latest main via merge commit f29ee31f1f.
• Validation rerun: make agent-report-progress, make test, make lint-cjs, focused pre_create_pull_request.test.cjs, focused eslint-factory rule test, automated code review, CodeQL JavaScript scan, and secret scan all passed.
• CI triage: current-head CJS failure was root-caused to formatting in eslint-factory/src/rules/no-exec-interpolated-command.test.ts and fixed in 1b6b353c52; current-head CGO failure had no individual test failure and ended with error generating coverage report: write |1: file already closed, so it appears infra/coverage-output related and was not reproduced locally (make test passed).

Resolved on current head f9327bf2ac.

• Title feedback: actions/setup/js/pre_create_pull_request.cjs now sanitizes the prefix/workflow title text and truncates it to the remaining GitHub title budget before prepending the invariant [WIP] marker, so the final pre-created PR title cannot exceed 256 characters while preserving [WIP].
• Tests: added coverage for long workflow names/title prefixes producing a 256-character PR title, no truncation notice in the title, mention sanitization in the assembled title, and the default sanitizeTitle 128-character limit.
• Body feedback: already addressed by actions/setup/md/pre_created_pull_request_body.md rendered through renderTemplateFromFile; MCP reports that review thread is resolved.
• Branch/CI: branch is refreshed on current base; MCP reports no status contexts/check runs on the pushed agent head, so CI needs a maintainer re-trigger.
• Validation rerun: focused CJS tests (pre_create_pull_request.test.cjs, sanitize_title.test.cjs) passed; make agent-report-progress passed on latest head; secret scan passed; automated code review rerun; CodeQL reported no analyzable supported-language changes.
