docs: comprehensive documentation accuracy and onboarding improvements

[doctor]

Summary

• New guides: Go2 quickstart, Innate bot, and Teleoperation docs
• Accuracy fixes: Line-by-line audit of all docs against code — fixed broken paths, incorrect CLI flags, wrong state dimensions, incomplete API signatures, stale READMEs, and misleading descriptions
• Onboarding improvements: Added Contributing section to README, start-here guidance in docs index, clarified examples directory split, rewrote cli/README.md to match actual commands
• API fix: Re-exported SO101_CONFIG, GO2_CONFIG, G1_CONFIG, INNATE_CONFIG from rfx package root so rfx.SO101_CONFIG works as documented
• Formatting: Applied ruff format to collection and runtime CLI modules
