Expose configured MCP servers from the CLI

PARITY.md called out missing MCP management in the Rust CLI, so this adds a focused read-only /mcp path instead of expanding the broader config surface first.

The new command works in the REPL, with --resume, and as a direct 7⠋ 🦀 Thinking...8✘ ❌ Request failed
 entrypoint. It lists merged MCP server definitions, supports detailed inspection for one server, and adds targeted tests for parsing, help text, completion hints, and config-backed rendering.

Constraint: Keep the enhancement inside the existing Rust slash-command architecture
Rejected: Extend /config with a raw mcp dump only | less discoverable than a dedicated MCP workflow
Confidence: high
Scope-risk: narrow
Directive: Keep /mcp read-only unless MCP lifecycle commands gain shared runtime orchestration
