Implement comprehensive content moderation and community protection

- Added Code of Conduct with clear behavioral standards
- Created Contributing guidelines with submission requirements
- Implemented structured issue templates (bug reports, features, new agents, moderation)
- Disabled blank issues to enforce template usage
- Added automated content moderation via GitHub Actions:
  * Real-time scanning for hate speech, threats, and profanity
  * Automatic closure/locking of critical violations
  * Moderation alerts for maintainer review
- Set up welcome system for new contributors with community guidelines
- Enabled GitHub Discussions as alternative to issues for general questions
- Closed and locked existing hate speech issue #30
- Blocked offending user account

This creates a multi-layered defense against inappropriate content while
maintaining an open, welcoming environment for legitimate contributors.
