feat: provider audit — builder support, function tuning, source archive

Аудит провайдера vs каноничный Fission. Добавлено:

Environment:
- builder_image, builder_command для Go и языков с build step

Package:
- deploy_type (literal/source) для переключения deployment/source archive
- loadPackageSourceArchive() — zip-упаковка source_dir
- Убран пустой source:{} из literal mode

Function:
- executor_type (poolmgr/newdeploy/container)
- function_timeout, idle_timeout
- min_scale, max_scale для ExecutionStrategy

Все 21 тест пройден. Обратная совместимость проверена.
