19e3047282 feat: rebrand to SecureBit.chat due to name conflict
BREAKING CHANGE: Project renamed from LockBit.chat to SecureBit.chat

- Changed project name to avoid confusion with LockBit ransomware group
- Updated all documentation, branding, and references
- Maintained all existing functionality and security features
- Domain migration planned to securebit.chat

Reason: The LockBit name became associated with a notorious ransomware
group, causing conflicts on platforms and potential confusion for users.
SecureBit better reflects our mission of providing secure P2P messaging
while avoiding negative associations.

This change affects:
- README.md and all documentation
- Package.json name field
- Brand assets and logos
- Website references
- Social media handles

Core functionality remains unchanged:
 12-layer military-grade security
 Lightning Network integration
 P2P WebRTC architecture
