Implement virtual tools feature to allow GitHub Copilot models to run with more than 128 tools

[thesobercoder]

Currently, GitHub Copilot models are restricted to a maximum of 128 tools configured. If you have more than 128 tools configured in OpenCode, then the API calls fail. To overcome this limitation, the VSCode team implemented a virtual tool concept that automatically activates them on demand. This is a proposal to implement something similar in OpenCode so that configuring more than 128 tools in OpenCode with GitHub Copilot does not fail with an API call.

Is there a fix planned or a work around available?

This isn't a super high priority for us currently but we will prolly have something for that eventually.

I suppose for the time being we can implement some warning or error toast specifically for copilot

This feature will really help if you can add a virtual tool for copilot!!
