Description 500 -> 211 chars, body 676 -> 462 words, Gotchas 5 entries/41% of
body -> 3/21%. Clears the description FAIL and both Gotchas suggestions.
Cut the second trigger register (the re-quoted user phrasings), the doubled
capability enumeration across releases and tags, and the gitea-issues/gitea-prs
boundary, which defended against nothing -- neither was going to win a release
request. Kept the indirect trigger and the one real near-miss, gitea-branches.
Releases and tags are one flow, not two: 'delete the release and its tag' is a
single invocation that takes both branches, which disqualifies mutual
exclusivity, so no dispatch split. Two Gotchas moved to references/ behind
explicit triggers; one deleted as a paraphrase of the step below it.
