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.
