- system-context-manager (new skill): stack-based project focusing with
push-context/pop-context, path resolution relative to base path, and
scope-aware memory queries via context-scoped-query.
- core-memory: add :scope slot to memory-object struct (default :memex).
- core-memory: ingest-ast accepts &key (scope :memex), propagates to children.
- core-context: context-query accepts :scope parameter for filtering.
- DEFECT FIX: renamed org-object-* accessors to memory-object-*
across core-context, security-dispatcher, tests, and defpackage exports.
The struct was renamed but accessor references were never updated —
the code referenced nonexistent functions.
