feat(tri): ci baseline — which PR gates have never run on the branch they gate (Closes 2309)

[gHashTag]

Closes #2309. Follow-up to #2276.

gHashTag/t27 (default branch master)
  PR-gated workflows: 28
  of those, never run on master by any event: 3
     check-now-freshness.yml
     loop-tools-gate.yml
     seal-staleness-warn.yml

Two wrong answers came first, and they are why the command reports what it reports. Reading triggers alone flagged 47 workflows because their push: carries a paths: filter — not a hole; a filtered push still runs on the default branch when those paths change, which is the sparse baseline tri pr ready already walks commits to find. Counting default-branch runs alone flagged 46 — also not holes; release pipelines, tag-triggered signing, nightly schedules and dispatch-only builds are supposed to have none and cannot paint a pull request red.

The finding is the intersection: PR-gated and never run on the default branch by any event. Across t27, trinity-fpga and zig-golden-float: 4. trinity-fpga (51 active PR gates) and zig-golden-float have zero.

The fourth, catalog-count-gate.yml, declared workflow_dispatch; one dispatch on master gave it a baseline and it left the list.

It refuses to grade the survivors, because three different things hide in such a list — a configuration hole (seal-staleness-warn, whose question is answerable on master and never asked there), one that is inherently pull-request-scoped and correct as it stands (check-now-freshness), and one whose push: paths simply have not changed on master yet (loop-tools-gate). Grading them automatically is how a useful sweep turns back into 47 false accusations.

The trigger scan is a text scan rather than a YAML parse on purpose: on: is a YAML 1.1 boolean, so a parser returns the key true, a lookup of "on" finds nothing in every file, and the sweep reports a clean repository because it read nothing. Its own test caught a missing inline-list spelling (on: [push, pull_request]) before this shipped.

Superseded by #2312: the commit subject here said Closes 2309 without the #, which L1 TRACEABILITY correctly rejected. Rebuilt on a fresh branch rather than force-pushed.
