v0.2.0

Added

• Multi-Workspace Memory Isolation:
  • Added workspace_id parameter to kache_save_context, kache_semantic_search, and kache_delete to provide segregated vector index namespaces ({index_name}:{workspace_id}) across different workspaces and projects.
• Native Telemetry Dogfooding:
  • Dogfood native KacheDB atomic keys (kachedb:telemetry:*) for cumulative tracker metrics, tracking hits, misses, tokens saved, and avoided latency without external SQLite or disk-based JSON persistence.
• KacheDB Server & SDK v0.1.1 Parity:
  • Updated dependency to kachedb>=0.1.1 to leverage latest vector indexing and buffer zero-copy stability.
  • Added pythonpath = ["src"] to pytest configuration for reliable local development and test execution.
