crosslink init --force adds agent-prompt MCP entry but does not create the server .py file

[maxine-at-forecast]

Bug

Running crosslink init --force updates .mcp.json to include the crosslink-agent-prompt MCP server entry, but does not write the corresponding Python server file to disk.

This leaves the MCP configuration pointing at a file that doesn't exist, causing the server to fail to start.

Steps to reproduce

1. Run crosslink init --force in a project
2. Observe .mcp.json now references crosslink-agent-prompt
3. The referenced .py file is missing from the filesystem

Expected behavior

Either:

• crosslink init --force should also create/copy the agent-prompt server .py file, or
• It should not add the MCP entry if the file isn't being created

Environment

• crosslink installed via uv
• macOS
