A time-boxed waiver for CVE-2026-84782 (HIGH), which started failing the required

This is a
.trivyignore.yamlentry in the formatdocs/runbooks/vulnerability-scanning.mdrequires: a statement, plusexpired_at: 2026-10-07, which is 7 days. If MCR hasn't published a rebuilt image by then, the finding re-blocks and gets reviewed again. If it has, the next scan passes without the waiver, and the entry can be removed at the next touch.Kept separate from #179 on purpose, so that a security exception is reviewable on its own rather than tucked into a CI change (decision: dsearle).
Verification: this PR's own
image-cverun is the test that Trivy honours the entry.🤖 Generated with Claude Code
