Add NoColorExpansion correction rule that rewrites --no-color into the two-arg form --color never, matching clap's expected syntax. The caller detects the rule variant and inserts the second arg. Also: add --lock to the sync command's known flags, and remove --format from the notes command's known flags (format selection was removed). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
