Runs the tmux MCP server over stdin and stdout.

An MCP client launches this as a subprocess and speaks JSON-RPC over its standard streams, so
**nothing may write to stdout but the protocol**. Diagnostics go to stderr, which the
client is free to log or discard.

Which tmux server to expose is chosen the same way the library chooses it: a socket path, a
socket name, or tmux's own default.

The unordered toolset and named-tool environment variables resolve one immutable surface
before tmux is opened. A tool outside it is neither listed nor callable.

## Example

```java
libtmux-mcp --socket /run/user/1000/tmux/default
libtmux-mcp --socket-name work --tmux /usr/local/bin/tmux
```
