feat(ci): aggiungi varianti -github dei reusable e fix audit Python

- crea gemelli X-github.yml per ogni reusable con action da github.com (fallback mirror gitea.com)
- python-dependency-check/outdated: audit in venv isolata (fix falsi positivi da runner ML)
- python-dependency-check/outdated: deduplica issue (commento invece di nuova issue)
- examples: aggiungi ci-github.yml e release-github.yml in tutte le cartelle

Fixes #3 @3h
