"""
Farnsworth VS Code Integration (LSP Server).
"I am the ghost in your machine!"
This module implements a partial Language Server Protocol (LSP) to allow Farnsworth
to communicate directly with VS Code.
Features:
1. Code Lenses: Show "Ask Farnsworth" above functions.
2. Diagnostics: Push analysis/Critique directly to the "Problems" tab.
3. Code Actions: "Refactor with Farnsworth".
