docs(xml): fill missing XML doc comments + strip task-tracking refs across src (fixdocs)

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.
