One scoped read that answers "is anything waiting to be deployed?" for the whole
fleet: each site's stored artifact revision hash compared against what a deploy
would send right now (NeverDeployed / Current / OutOfDate), plus per-site
deployed/stale/unknown instance tallies from the batched staleness evaluation.
NeverDeployed is deliberately NOT a pending update — the operator has not deployed
yet — and exceptions propagate so the caller's single-flight cache can render
"unavailable" rather than invent an "up to date". Adds the validated
PendingUpdatesCacheTtl (60 s) that TTL will key off.

Remove project bookkeeping citations from shipped code comments across the
solution: hyphenated task IDs (WP-14, StoreAndForward-025), milestone/task/
issue refs (M3, Task 4, Audit Log #23, #21), Bundle X task-bundle labels,
and C/D/K/S/T phase labels.
Comment text only — no code logic, string/log literals, or XML-doc structure
changed. Genuine descriptions are preserved (only the citation is stripped),
and technical lookalikes are retained (UTF-8, SHA-256, T00:00:00, M365,
UTC-5, pre-C4/pre-C5 schema versions). Flagged by the new CommentChecker
TaskReferenceInComment / TrackingReferenceInComment checks plus targeted
grep passes; full solution builds clean, append-only guard tests pass.
