gate-topology is red on every PR: the feeder workflow was classified by nobody

[gHashTag]

What is wrong

gate-topology fails on every open pull request:

Unclassified workflows carrying a pull_request branch filter: 0
UNCLASSIFIED ROSE 24 -> 25
  A workflow was added and named in neither list, so this check
  does not read it.

The twenty-fifth is queen-feed-untested.yml, merged an hour ago in #4307. The
gate exists precisely so that a workflow cannot arrive unread, and it caught it.

What to write

It belongs in NOT_MERGE_CRITICAL for the same reason its sibling
queen-feed-empty-bodies.yml does: it opens issues on a schedule and its own
failure gates no merge. Classifying it returns the count to the ceiling rather
than raising the ceiling.

Acceptance criteria

• 1. python3 scripts/ci/check_pr_branch_filters.py prints a line beginning CLEAN: (today: it prints UNCLASSIFIED ROSE 24 -> 25)
• 2. grep -c 'queen-feed-untested' scripts/ci/check_pr_branch_filters.py prints 1 (today: 0)
• 3. grep -c 'MAX_UNCLASSIFIED = 24' scripts/ci/check_pr_branch_filters.py prints 1 - the ceiling must not be raised to bless this
