fix(server): PR watch reports all checks passed while CI workflows are queued #34550

On 2026-11-11, the native PR watch for #31032 reported All 1 check passed on 1c8d785.

Same-session GitHub readback on full head 1c8d785f935e9d72418c5355798b1d29e50ddf26 showed only CodeRabbit in statusCheckRollup, with conclusion SKIPPED. The Actions API showed CI, Agent Context Budget and preview workflows still queued. For example: https://github.com/pingdotgg/t3code/actions/runs/43098842035 . No build/test result had reported.

Expected: report CI pending when workflows are queued without check-run entries; a lone skipped review must not produce an all-checks-passed notification. Classification cause is unproven; no code investigation performed. Related closed #24575 concerns approval-gated runs rather than the queued runs observed here.
