Subject: [PATCH] fix: Change memory server default filename from memory.json
 to memory.jsonl

The Memory MCP server uses JSONL format (JSON Lines) where each line
contains a separate JSON object, but was using a .json file extension.
This caused IDE lint errors and confusion since the file is not valid JSON.

Changes:
- Update default filename in index.ts from memory.json to memory.jsonl
- Update documentation references in README.md
- Maintain backward compatibility for existing MEMORY_FILE_PATH configs

Fixes #2361
