close-invalid-pr-template.yml now comments and labels (missing pr template,
stale) instead of closing immediately, clears itself once fixed. stale_pr_close.yml
gains the engagement-gated/keep-open/maintainer-reset behavior already used in
DevScripts, so a template-stale PR only closes via its own re-check.
request-script.yml discussion template gets an optional Justification field;
a new workflow verifies stars/age against GitHub for the submitted repo and
either does nothing (eligible), labels investigation (ineligible + justified),
or closes the discussion (ineligible, no justification).
Moved the AI Assistance section to the end of pull_request_template.md.
