`has_customization` uses `\s` while the rest of the codebase uses `[[:space:]]`

Non-Blocking Review Concern: has_customization uses \s while the rest of the codebase uses [[:space:]]

Source: pre-push whole-codebase review
Location: bulk-install-claude-review.sh:149
Date: 2026-04-30

What was flagged

The new script uses ^\s* in has_customization, while claude-review-audit.sh and the rest of bulk-install-claude-review.sh itself consistently use POSIX [[:space:]]. macOS BSD grep -E does support \s in modern releases, but the inconsistency is a portability/style smell — and if the regex ever silently fails to match leading whitespace under a different grep variant, customized callers will be falsely classified as un-customized and get auto-bumped, defeating the whole "human review" guard. Replace with ^[[:space:]]* to match the codebase convention.
