Add Docker deployment option for the server with multi-stage build.
Changes:
- Dockerfile: multi-stage build (golang:1.26-alpine → alpine:3.21, ~23MB)
- docker-compose.yml: server service on port 5300/udp with iptables redirect
- .env.example: documented environment variables template
- .dockerignore: optimized build context
- README.md & README-FA.md: Docker deployment guide, port 53 safety checks,
and troubleshooting instructions (both EN and FA)
- configs: added more Telegram channels and X accounts
The container listens on port 5300 to avoid conflict with systemd-resolved.
External DNS traffic (port 53) is redirected via iptables PREROUTING.
No changes to existing Go source code.
- Implemented /api/cache/clear endpoint to delete all files in the cache directory.
- Added tests for cache clear functionality, including cases for empty cache and method not allowed.
- Introduced /api/rescan endpoint to trigger a manual rescan of the configured channels.
- Added tests for rescan functionality, covering cases for not configured, method not allowed, and successful rescans.
- Enhanced server initialization to bootstrap configuration from active profile if config.json is missing.
- Refactor fetcher tests to improve coverage and add new tests for resolver scoring and query handling.
- Update ResolverChecker to retry every minute until a healthy resolver is found and adjust timeout settings.
- Introduce scatter parameter in the configuration to allow concurrent DNS requests, with UI adjustments for user input.
- Modify metadata fetching logic to utilize cached data efficiently and ensure fresh data is fetched when necessary.
- Implement server-side handling for fetch progress, including countdowns and UI updates during long fetch operations.
- Added Profile and ProfileList structs to manage user profiles with unique IDs and nicknames.
- Introduced endpoints for CRUD operations on profiles: `/api/profiles` for managing profiles and `/api/profiles/switch` for switching active profiles.
- Implemented settings management with an endpoint `/api/settings` to handle user preferences like font size and debug mode.
- Enhanced the server to load and save profiles from a `profiles.json` file.
- Updated the fetcher initialization to respect the active profile's configuration.
