This comprehensive implementation includes CLI orchestration, browser integration, server infrastructure, and a novel gasless transaction architecture that allows users to create their first decentralized identity without requiring existing tokens.\n\nFixes #160\n\n## 🚀 Key Features Implemented\n\n### WebAuthn CLI Registration Flow\n- **Hybrid Architecture**: CLI spawns local HTTP server, launches browser for WebAuthn ceremony\n- **Channel Synchronization**: Go channel coordination between CLI and server components  \n- **Timeout Protection**: 10-second CLI timeout with 15-second server failsafe\n- **Cross-platform**: Browser opening support across operating systems\n\n### Gasless Transaction Architecture\n- **Custom AnteDecorators**: WebAuthn-specific transaction identification and validation\n- **Fee Waiving Logic**: Conditional fee bypass for qualifying WebAuthn registration transactions\n- **Security Validation**: Cryptographic credential validation to prevent abuse\n- **Anti-Replay Protection**: Credential ID uniqueness checking prevents reuse attacks\n\n### Enhanced Protobuf Schemas\n- **WebAuthn Credential Types**: Comprehensive W3C-compliant credential structures\n- **Transaction Messages**: Dedicated \\`MsgRegisterWebAuthnCredential\\` for WebAuthn registration\n- **Query Methods**: \\`GetWebAuthnCredentials\\` and \\`ListWebAuthnCredentials\\` with pagination\n- **Configuration Parameters**: WebAuthn timeout, origins, algorithms, RP settings\n\n## 🔧 Implementation Details\n\n### Core Components\n- \\`app/commands/auth_register.go\\` - CLI orchestration with server lifecycle management\n- \\`app/server/handlers.go\\` - WebAuthn HTTP handlers with embedded HTML templates\n- \\`app/ante/webauthn_decorator.go\\` - Gasless transaction AnteDecorator implementation\n- \\`x/did/types/webauthn.go\\` - WebAuthn credential validation as struct methods\n\n### Security Architecture\n**Gasless Transaction Eligibility:**\n1. Single \\`MsgRegisterWebAuthnCredential\\` message only\n2. Full cryptographic credential validation (ES256/RS256)\n3. Global credential ID uniqueness enforcement\n4. Account existence verification with auto-creation\n5. WebAuthn inherent anti-abuse properties (user presence, device binding)\n\n### Breaking Changes\n- **Protobuf Schema Updates**: Enhanced WebAuthn credential types in \\`proto/did/v1/\\`\n- **New Transaction Types**: \\`MsgRegisterWebAuthnCredential\\` message type\n- **Ante Handler Chain**: Modified transaction processing flow for gasless support\n\n## 🧪 Testing Status\n\n### ✅ Completed Implementation\n- [x] CLI-to-browser WebAuthn workflow with timeout handling\n- [x] Server infrastructure with embedded HTML templates and JavaScript\n- [x] Gasless transaction architecture with security validation\n- [x] Enhanced protobuf schemas with comprehensive WebAuthn support\n- [x] Base64url encoding compliance (RFC 4648 Section 5)\n- [x] Cross-platform browser integration\n- [x] Channel-based CLI/server synchronization\n\n### 🔄 Pending Implementation Tasks\n\nBased on PLAN.md analysis, the following tasks remain for full completion:\n\n#### Final Integration (15% remaining)\n- [ ] \\`x/did/keeper/msg_server.go\\` - Complete RegisterWebAuthnCredential RPC handler implementation\n- [ ] \\`x/did/keeper/query_server.go\\` - Complete GetWebAuthnCredentials and ListWebAuthnCredentials handlers\n- [ ] \\`app/server/handlers.go\\` - Bridge server handlers to existing keeper WebAuthn methods\n- [ ] \\`x/dwn/keeper/keeper.go\\` - Auto-vault creation integration for WebAuthn registration\n\n#### Comprehensive Testing Suite\n- [ ] Server infrastructure extension tests\n- [ ] CLI orchestration and lifecycle tests  \n- [ ] WebAuthn challenge generation and validation tests\n- [ ] Browser-server communication API tests\n- [ ] Gasless transaction flow integration tests\n- [ ] Security validation and anti-abuse tests\n- [ ] Cross-platform browser opening tests\n- [ ] Error hand
