"""
Shared FastMCP instance for Daem0nMCP.
This module provides the singleton FastMCP instance that all tool modules
register their @mcp.tool decorators against. It sits at the bottom of the
import hierarchy to break circular imports:
mcp_instance (this module -- zero business-logic imports)
<- context_manager (ProjectContext lifecycle)
<- tools/* (tool definitions import mcp + context_manager)
<- server.py (composition root wires everything together)
By isolating the FastMCP instance here, tool modules can be extracted from
server.py without creating circular dependencies.
