Agents not Recognized loading plugin with only .copilot repository Or hooks not found with com.github.copilot

Does this issue occur when all extensions are disabled?: Yes/No

- VS Code Version: Insider
- OS Version:

When building a plugin, the recomendation is com.github.copilot. So having only a .copilot/ does not work (I.E - The agents are not recognized.)

I'm not sure which is the better here, maybe loading hooks and things from com.github.copilot also?

Figure 1 - I do have com.github.copilot but I do not have .copilot (so the hooks are not found, and it defaults to .copilot for everything. ) - Hence nothing load for copilot - instructions are skept.

Steps to Reproduce:

1. create a plugin
2. add a .copilot only ( and watch that no agents load. )
3. add a com.github.copilot only ( and watch that no hooks, instructions and etc are loaded ).
