v1.4.5: Graph Blast-Radius Analysis & Multi-Project Facts Auto-Supersede

Enhancements in v1.4.5

• Multi-Hop Graph Blast-Radius Traversal: New endpoint GET /graph/blast-radius, MCP primitive get_blast_radius, and SDK client methods (Friday.get_blast_radius / AsyncFriday.get_blast_radius) with safe offline fallback when Neo4j is unavailable.
• Smart Conflict Resolution & Auto-Supersede: Facts ledger automatically detects key collisions (Key: Value) within project namespaces to supersede obsolete facts, eliminating prompt bloat and agent hallucinations.
• Project Isolation: Granular multi-project scoping (reeldm, friday, global) across facts and persona export.
• Packaging Integrity: 100% Hatchling strict sdist and wheel whitelist ensuring zero internal leaks.
