Feature request: dedicated MCP servers tab in the TUI

[hugosenari]

Description

There is currently no dedicated tab or view in the vix TUI that lists all configured MCP servers in one place.

Currently, to check which MCP servers are configured you have to:

1. Read settings.json files manually
2. Watch daemon logs for startup messages
3. Or infer a server is connected only when the agent calls one of its tools

Proposed feature

A dedicated tab (e.g. under F4 or a new F-key) that shows:

• All configured MCP servers with their status
• Server type (stdio vs url)
• Tool count per server
• Option to enable/disable individual servers

Current workaround

Reading the mcp_servers array from settings.json and watching daemon logs.

This will be added in the next version v0.5.6. Keeping the issue open in the meantime to keep track.
