- Pass the /ask question to claude on stdin so it can't be parsed as a CLI option.
- Block run_lua in multiplayer unless an admin enables the new
"Allow Lua queries in multiplayer" map setting.
- Ignore UDP packets that don't come from the game's port, in both the
MCP server and the ask helper.
- Build the screenshot path from our own name instead of the game's reply,
and restrict screenshot names in the mod.
- Validate ask packets, cap question length and limit concurrent claude runs.
- Replace hard-coded home paths in the README and systemd unit.
