Support for MCP Proxy flag

[derogab]

llama-server includes a --ui-mcp-proxy flag (experimental MCP CORS proxy) that LlamaBarn doesn't currently expose. This is needed when connecting browser-based or remote MCP clients to the local server — without it, CORS policy blocks the requests.

Could this be surfaced via a defaults write setting and/or a checkbox in the Settings window?

[derogab]

Update (source): it's possible to set experimental MCP CORS proxy with

defaults write app.llama.Llama extraServerArgs -string "--ui-mcp-proxy"

[erusev]

The extraServerArgs setting above covers this, so I'll close it. Restart the app after changing it for the flag to take effect.
