Fixed then insertion to only trigger before known HS command keywords (set, put, add, remove, toggle, etc.) via lookahead regex, instead of on all multi-space sequences. Prevents breaking single-command expressions with wide spacing. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
