Subject: feat: switch config to JSON; add go.mod and config.json.example

- Replace Viper-based config with encoding/json (config.go)
- Add config.json with sensible defaults (gitignored)
- Add config.json.example with empty values as reference
- Initialize go module (go.mod)
- Update main.go to use LoadConfig()
