Cut commentary from 104 to 24 lines across the new lint script, CI config, and pre-push hook. Kept only: policy reference, why pattern is loose, why scope is PR commits not history, and non-obvious CI behavior notes. No logic lines changed. Refs #4432

# Flags Co-Authored-By trailers with Claude/Anthropic attribution in PR commits.
|
|
# The hive convention in /knowledge/hive-rules.md forbids these trailers.
|
|
#
|
|
# Pattern is loose (case-insensitive, matches `claude`, `anthropic`, or
|
|
# `noreply@anthropic.com` anywhere after `co-authored-by`) to cover variants
|
|
# like `Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>`.
|
|
#
|
|
# Scope is the PR's commits (BASE..HEAD), not entire history — old commits
|
|
# must not fail the build.
