v0.14.0

v0.14.0 — Topology-aware activate & Graph audit

Highlights

Topology-aware activate (#100) — activate now walks claim_links and entity→relation→entity→claim paths to build connected subgraphs, not just top-k similar claims. Edge semantics are direction-aware (supports/extends=forward, related=both, contradicts=flag, supersedes=shadow).

Graph audit — New pce_memory_graph_audit tool detects orphan claims/entities, contradiction cycles, supersession chain debt, scope holes, generic hubs, and repeated co-activations without edges.

Rollback blast radius — pce_memory_rollback now returns topology-derived blast radius with connected claims, linked entities, affected active contexts, and support/conflict/supersession neighborhoods with path information.
