In gateway mode the bot's Claude Code CLI was spawned with cwd set to
a nonexistent project subdirectory (gateway_config_dir/project_name).
This meant it couldn't find .mcp.json and had no MCP tools available.
Now the bot uses the gateway config directory as cwd in gateway mode,
where the auto-generated .mcp.json points to the gateway's MCP proxy.
Also fixes cargo fmt formatting.
