MCP Tools Bug Fix - newline parameter

Issue

The MCP edit_file tool in src/mcp_client.py was using newline="" in read_text() and write_text() calls. This parameter is NOT supported by Python's pathlib.Path methods before Python 3.10.

Fix Applied

Removed all newline="" parameters from:

• p.read_text(encoding="utf-8", newline="") → p.read_text(encoding="utf-8")
• p.write_text(content, encoding="utf-8", newline="") → p.write_text(content, encoding="utf-8")

Prevention

When editing Python files via MCP tools, always use the standard encoding="utf-8" without the newline parameter, as Python's pathlib doesn't support it until 3.10+.
