Sweep every first-party crate source (1956 .rs files) to the project comment guidelines: delete redundant restatements, decorative banners, change narration, and end-of-line comments; keep and tighten the crucial ones (invariants, bug rationale, SAFETY blocks, ported-source attribution). No functional code changed. Every edit is proven comment-only against the prior tree by a comment-stripping lexer (string/char/raw-string aware) plus a separate doctest-fence check. Where removing a comment made rustfmt or clippy want to re-lay-out adjacent code, the minimal triggering comment is restored so code tokens stay byte-identical. Gates green: cargo fmt --all --check (0 diffs), cargo check and cargo clippy --workspace --all-targets (0 warnings). Adds scripts/check_codegen_comment_guidelines.py — the enforcement gate for these guidelines (flags banners, end-of-line comments, change narration, and commented-out code).
