mcp wraps any CLI as MCP server

This is a practical bridge for the MCP era: most useful software is still shipped as CLIs, and this makes them reachable by agents without rewriting integrations.

• –The zero-code config is the real win; one `cli: true` entry can surface tools for `kubectl`, `docker`, `terraform`, `git`, and `gh`.
• –The `cli_only` whitelist is essential, because a generic wrapper around powerful CLIs can become dangerous fast.
• –Proxy mode is a smart second act: one MCP connection, lazy backend startup, and less idle-process churn for local setups.
• –The hard part will be schema fidelity; parsing `--help` is clever, but inconsistent help text and nested command patterns will determine how reliable this feels across tools.
