Walkthrough

The LSP workspace database now shares and removes cached parsed sources during path unloading. File closure removes the matching parsed source. Project closure removes parsed sources and plugin caches under the project path while preserving sibling-project caches. Regression tests cover these cases. A changeset records a patch release for the memory-leak fix.

Merge Risk: ⚪ Minimal · up to 6f882

This change fixes file-cache eviction when files are closed and adds regression coverage. The remaining documentation-only cleanup does not affect runtime behavior, so no actionable merge-blocking risk remains.
