Add an activation command for other extensions

Since VS Code provides no actionEvents that trigger when a specific
extension activates, extensions can't activate only once Roo is
activated and ready.

This commit introduces a new roo-cline.activationCompleted command
and fires it at the very end of extension activation. Other
extensions that use Roo's exported APIs can now activate when they
see this event.
