Add missing <summary>/<param>/<returns>/<typeparam> tags and switch interface implementations to <inheritdoc/> across 106 files; strip project bookkeeping identifiers (Task NN, #05-TNN, PLAN-04, StoreAndForward-0NN) from shipped code comments while preserving the descriptive rationale. Comment-only: zero code-logic lines changed; solution builds 0/0. Claude-Session: https://claude.ai/code/session_01MtdgwpEeCUn6cUA5f1LMPj
