RTT channels are not processed

[excieve]

It appears that there's currently no RTT support in this extension. When the debugger task is running, RTT messages in the configured channels are not being read. At the same time rtthost is able to read them just fine.

I understand this is due to the extension not emitting the custom rttWindowOpened command, which is necessary to start the polling:

Please add support for this feature by reading at least the channel 0 and writing the data from it to the console or terminal panels of the debugger dock.

Is this even something the extension could do currently or should this be fixed in Zed? Unless the documentation is bad, it seems like there's no method for an extension to emit commands or do something with terminals or other panels?

So maybe we should open an issue at Zed.
