Rename CLIENT events to HOST in Bridge event system

[Copilot]

The CLIENT_* event names in the Bridge system were ambiguous—they refer to physical machines/containers connecting to the Bridge, not Discord clients.

Changes

• Renamed three Bridge events:

  • CLIENT_CONNECTED → HOST_CONNECTED
  • CLIENT_DISCONNECTED → HOST_DISCONNECTED
  • CLIENT_STOP → HOST_STOP

• Updated BridgeEventListeners type definition and all event triggers in Bridge.ts

This affects the public API for Bridge event listeners:

// Before
bridge.on('CLIENT_CONNECTED', (client: BridgeClientConnection) => { ... });

// After
bridge.on('HOST_CONNECTED', (client: BridgeClientConnection) => { ... });

<issue_description>The usage of CLIENT is very confusing.
To make it clear what is meant, the CLIENT-Keyword should be renamed to HOST since a physical machine/container is meant.</issue_description>
