v0.4.9 - Working on dm admin

- Add cache refresh mechanism for config updates
- Implement selective re-initialization for NIP-11 relay info changes
- Categorize configs as dynamic vs restart-required using requires_restart field
- Enhance admin API responses with restart requirement information
- Add comprehensive test for dynamic config updates
- Update documentation for dynamic configuration capabilities

Most relay settings can now be updated via admin API without requiring restart, improving operational flexibility while maintaining stability for critical changes.

+## 🌐 Web Admin Interface
+
+C-Relay includes a **built-in web-based administration interface** accessible at `http://localhost:8888/api/`. The interface provides:
+
+- **Real-time Configuration Management**: View and edit all relay settings through a web UI
+- **Database Statistics Dashboard**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **NIP-42 Authentication**: Secure access using your Nostr identity
+- **Event-Based Updates**: All changes are applied as cryptographically signed Nostr events
+
+The web interface serves embedded static files with no external dependencies and includes proper CORS headers for browser compatibility.

+### Dynamic Configuration Updates
+
+C-Relay supports **dynamic configuration updates** without requiring a restart for most settings. Configuration parameters are categorized as either **dynamic** (can be updated immediately) or **restart-required** (require relay restart to take effect).
+
+**Dynamic Configuration Parameters (No Restart Required):**
+- All relay information (NIP-11) settings: `relay_name`, `relay_description`, `relay_contact`, `relay_software`, `relay_version`, `supported_nips`, `language_tags`, `relay_countries`, `posting_policy`, `payments_url`
+- Authentication settings: `auth_enabled`, `nip42_auth_required`, `nip42_auth_required_kinds`, `nip42_challenge_timeout`
+- Subscription limits: `max_subscriptions_per_client`, `max_total_subscriptions`
+- Event validation limits: `max_event_tags`, `max_content_length`, `max_message_length`
+- Proof of Work settings: `pow_min_difficulty`, `pow_mode`
+- Event expiration settings: `nip40_expiration_enabled`, `nip40_expiration_strict`, `nip40_expiration_filter`, `nip40_expiration_grace_period`
+
+**Restart-Required Configuration Parameters:**
+- Connection settings: `max_connections`, `relay_port`
+- Database and core system settings
+
+When updating configuration, the admin API response will indicate whether a restart is required for each parameter. Dynamic updates take effect immediately and are reflected in NIP-11 relay information documents without restart.

 Your relay is now available at:
 - **WebSocket**: `ws://localhost:8888`
-- **NIP-11 Info**: `http://localhost:8888`
+- **NIP-11 Info**: `http://localhost:8888` (with `Accept: application/nostr+json` header)
+- **Web Admin Interface**: `http://localhost:8888/api/` (serves embedded admin interface)
 
 ## Installation

 | `nip40_expiration_filter` | Filter expired events | "true" | "true", "false" |
 | `nip40_expiration_grace_period` | Grace period (seconds) | "300" | 0-86400 |
 
+## Web Admin Interface
+
+The relay includes a built-in web-based administration interface that provides a user-friendly way to manage your relay without command-line tools.
+
+### Accessing the Interface
+
+1. **Open your browser** and navigate to: `http://localhost:8888/api/`
+2. **Authenticate** using your Nostr identity (the admin interface uses NIP-42 authentication)
+3. **Manage configuration** through the web interface
+
+### Features
+
+- **Real-time Configuration**: View and edit all relay settings
+- **Database Statistics**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **Relay Connection Testing**: Verify WebSocket connectivity and NIP-11 information
+- **Event-Based Updates**: All changes are applied as signed Nostr events
+
+### Security Notes
+
+- The web interface requires NIP-42 authentication with your admin pubkey
+- All configuration changes are cryptographically signed
+- The interface serves embedded static files (no external dependencies)
+- CORS headers are included for proper browser operation
+
+### Browser Compatibility
+
+The admin interface works with modern browsers that support:
+- WebSocket connections
+- ES6 JavaScript features
+- Modern CSS Grid and Flexbox layouts
+
