feat: implement XEP-0077 In-Band Registration support
- Add XEPFeatures framework for managing XMPP extension protocols - Implement complete XEP-0077 In-Band Registration functionality - Add server capability detection using disco#info queries - Only initialize XEP features when server supports them - Add comprehensive XEP-0077 testing to doctor command - Doctor tests create and delete test users to validate functionality - Add struct-based XEP management instead of dynamic maps 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
