Fix PR duplicate check not running on external contributor submissions (#2188)

* Initial plan

* Fix PR duplicate check not running on external contributor submissions

Add forks: [\"*\"] and roles: all to pr-duplicate-check.md so the
agentic workflow runs for all PR authors, including external contributors
submitting from forks. Previously, the generated lock.yml contained:
- A fork repository check blocking all fork PRs from running
- A team membership check (admin/maintainer/write) blocking external contributors

Recompiled with gh aw compile to regenerate pr-duplicate-check.lock.yml.
The pre_activation job (which held the membership gate) is now removed,
and the activation job runs unconditionally for all pull_request events.

Closes #2121
