 * Merge loopgraph hook entries into a Claude Code `settings.json`.

 * delete-then-append. Any existing command whose text contains
 * "loopgraph hook" is removed (and a matcher group emptied by that removal
 * is dropped), then the current groups are appended — naturally idempotent
 * and upgradeable. Third-party hooks are never touched. Unparseable JSON is
 * never rewritten.
