Fixes critical data loss bug where creating similar entity names
(e.g., "Node C") would overwrite existing entities (e.g., "Node A.md")
due to fuzzy search incorrectly matching similar file paths.
Changes:
- Add strict=True to resolve_link() calls in entity_service.py
- Disables fuzzy search fallback during entity creation/update
- Prevents false positive matches on similar paths like
"edge-cases/Node A.md" and "edge-cases/Node C.md"
Testing:
- Added comprehensive integration test reproducing the bug scenario
- Added MCP-level permalink collision tests
- All 55 entity service tests pass
- Manual testing confirms fix prevents file overwrite
