feat(clawhubadapter): bridge OC channels to HomeAgent output/input channels

- registry.go: replace channelDevice+RegisterChannel with RegisterOutputChannel
  handler routes output via sp.CallTool to JS manager outbound handlers
  register {plugin}_read_{ch}_input tool for agent to poll buffered input
- plugin.go: handle channel_input notifications in translateAndRegister
  buffer payload in channelInputBuf + InjectInterruptText to notify agent
- manager/main.js: registerChannel supports {plugin: ChannelPlugin} format
  tools/call routes channel names to outbound.sendText/sendMedia
  submitInput sends channel_input notification to Go side
