Asim Aslam bba3b8ba98 ci: add govulncheck vulnerability gate (+ wire into loop triage) (#4558)
Adds a deterministic reachable-CVE gate: `govulncheck ./...` on every push/PR,
failing on any reachable vulnerability EXCEPT an explicit allow-list of
known-unfixable ones. Today the allow-list holds exactly the two pgx/v4 CVEs
(GO-2026-5004, GO-2026-4518) with no upstream fix (tracked in #4556), so the
gate is green now and turns red the moment a NEW vulnerability appears.

This is the deterministic layer under the `security` loop role: the role
audits with judgment, this blocks known CVEs mechanically. Also adds
`govulncheck` to the loop-triage watch list, so a newly-disclosed CVE that
reddens the gate on master auto-files a fix issue for the loop to bump the dep.

Make `govulncheck` a required status check on master to enforce it.
Verified locally: exit 3 with only the two allow-listed IDs -> gate PASS.

# Deterministic vulnerability gate: runs govulncheck (reachability-aware CVE
# scanner) on every push/PR. Fails on any reachable vulnerability EXCEPT the
# explicit ALLOWLIST of known-unfixable ones, so a new vuln breaks the build
# while tracked, no-upstream-fix ones don't. This is the gate the loop's
# `security` role sits on top of — the role audits; this blocks known CVEs.
#
# Make this a required status check on the default branch to enforce it.
