Across the 27-cycle review process, comments accumulated as multiline
blocks explaining each fix's history (cycle numbers, prior bugs,
reviewer rationale). Compress every block to 1-2 lines that capture
just the WHY, dropping cycle references and history that belongs in
the PR description / commit log instead.
Net: 268 deletions / 124 insertions (-144 lines) of comments only.
Behavior unchanged. Verified: bash -n, pwsh parser, python ast.parse,
cargo check all pass.
