Closes the §9.4 track:
- set_if (compare-and-swap), per-app and shared, now runs the same (kv, set)
before/after interceptor as set — otherwise CAS was a silent bypass of a set
policy. The before-hook can transform the new value; the after-hook sees the
swapped bool.
- read-only pic interceptors ls --app|--group: app shows the RESOLVED chain
(every marker guarding its writes, nearest-owner-wins), group its own markers.
New apply_service::interceptor_report + InterceptorInfo, /apps|groups/{id}/
interceptors routes (AppRead/GroupScriptsRead), client + cmd mirroring
extension-points.
CLAUDE.md updated: §9.4 service interceptors are now COMPLETE (M1-M12).
Pinned by a journey: set_if of a guarded key is denied while a free key swaps,
and interceptors ls lists the kv/set guard (12 interceptor journeys green).
