[FEATURE] Make TCP server bind address configurable

## Feature Description

Currently the bind address is hard coded to 127.0.0.1. If Claude Code is executed inside a container for example it cannot reach the websocket server.

## Use Case

Describe the context or use case for this feature. How would it benefit you and others?

Some companies such as the company I currently work for do not allow running Claude Code locally and enforce running it inside containers. Adding this configuration will allow using the plugin in such cases

## Proposed Solution

Adding bind_address to the plugin config and replacing the hard coded value. Default will remain 127.0.0.1 for security reasons.

No files or tests are named. Locate the TCP server bind entry point and the plugin configuration handling, then trace how the current 127.0.0.1 value is supplied. Done means a configurable bind_address is supported while 127.0.0.1 remains the default; add or update coverage if the project has tests for this path.
