The pr-pipeline workflow filtered both push and pull_request on
paths (**.prose.md, scripts/**.sh, **.yaml, **.yml). A PR whose diff
touched none of those paths — e.g. PR #77, deliverables/-only —
produced no Gitea Actions run at all, so validate/lint/ai-review and
the merge gate were silently skipped.
Remove the paths filter from both triggers and record in the file
that the trigger is intentionally unfiltered. No job, step, needs,
if or command is changed.
