bugfix(MCP): ensure memory path exists on initialization and remove unused… (#4418)

* bugfix: ensure memory path exists on initialization and remove unused everything mcp server

* refactor(factory): remove unused EverythingServer import and case

* fix(CodeCacheService): update import statement for LRUCache to default import

Error: src/renderer/src/services/CodeCacheService.ts(2,10): error TS2595: 'LRUCache' can only be imported by using a default import.
