Add JSON Pointer, Patch and Merge Patch#271
Merged

Conversation
jsonpath is read-only and approval compares whole artifacts, so nothing could address one location, compute a structured delta, or apply a partial update to a JSON document. Add the three IETF primitives: RFC 6901 JSON Pointer, RFC 6902 JSON Patch (all six ops, atomic apply, plus make_patch diffing), and RFC 7386 JSON Merge Patch. Pure stdlib, validated against the RFC test vectors. Wired through the facade, four AC_* executor commands, MCP tools and the Script Builder.

Summary
jsonpathis read-only andapprovalcompares whole artifacts by equality — nothing could address a single location, compute a structured delta, or apply a partial update to a JSON document. This adds the three IETF primitives that fill that gap.resolve_pointer/set_pointer/remove_pointer(with~0/~1escaping,-end-of-array token).apply_patch(all six ops add/remove/replace/move/copy/test, atomic — failure leaves the input untouched) andmake_patch(diff two docs).merge_patch(anullvalue deletes a key) andmake_merge_patch.testdoes deep equality keepingtruedistinct from1;moverejects moving a value into its own child. Pure stdlib (json+copy), fully deterministic, validated against the RFC test vectors. Useful for config-drift detection, partial updates in flows, HTTP PATCH bodies, and golden-master deltas.Five-layer wiring
