docs: fill missing XML docs and strip tracking IDs from src comments

Clears CommentChecker findings in src/ (3,280 -> 209, the remainder being false

normalising inheritdoc usage, and removing Gitea/review tracking IDs while keeping
the rationale they annotated. Comment-only: comment-stripped sources are identical
to the parent commit.
