Change default output to Unix socket

- config.yml.example: Unix socket enabled by default, stdout commented out
- internal/output/writers.go: Remove all internal logging from UnixSocketWriter
  and FileWriter - only LogRecord JSON data is sent to outputs
- architecture.yml: Update description to mention 'socket UNIX par défaut'
- packaging/rpm/ja4sentinel.spec: Bump version to 1.1.1, update changelog

Diagnostic logs (error, debug, warning) now only go to stdout when enabled.
