Michael Recachinas 925dc83735 Migrate pull request automation away from pull_request_target (#2625)
* Migrate pull_request_target workflows

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Address PR duplicate check writer review

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Fix duplicate-check writer artifact handling

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Make PR duplicate check gh-aw compilable

Configure the agentic workflow source to allow fork PR triggers with staged safe outputs, upload a PR context artifact through supported post-steps, and have the workflow_run writer consume that context before publishing validated comments. This lets gh-aw regenerate the lockfile without restoring pull_request_target or privileged PR-code execution.

* Harden workflow-run PR writers

Bind privileged artifact processing to trusted workflow-run PR identity, serialize same-PR writers, and cap aggregate quality comments.
