config: переезд на YAML вместо JSON + main ветка

- config.json → config.yaml (формат YAML)
- github.com/spf13/viper не нужен — используем gopkg.in/yaml.v3
- Поддержка .yaml и .yml расширений
- Флаг -config по умолчанию смотрит config.yaml
- config.local.{yaml,yml} добавлены в .gitignore
- Ветка переименована master → main
