It would be great to add support for Roo Code.

How similar or different is it from the config of Cline and/or Kilo Code? Any opportunity for re-use or is it completely different? (not a factor in the decision whether to add - we definitely should - just curious).

Comparison between Cline and Roo Code:

Description	Cline	Roo Code
Single Rule File	.clinerules	.roorules
Rule Folder	.clinerules/*	.roo/rules/*

Gave it a shot: #113 (made with roo ofc 😉).
