chore: add .python-version to templates missing it

[emberb170d]

Adds .python-version file (containing 3.12) to the 5 templates that were missing it:

• celery-worker
• cli-starter
• django-api
• fastapi-starter
• mlops-sklearn-starter

This aligns with the requires-python = ">=3.12" in each template's pyproject.toml and enables pyenv local / uv python pin auto-resolution for scaffolded projects.

Closes#153

Summary by CodeRabbit

• Chores
  • Standardized formatting conventions across project templates, including encoding, line endings, indentation, final newlines, and whitespace handling.
  • Added language-specific formatting rules for configuration, documentation, data files, and Makefiles.
  • Set Python 3.12 as the default version for the Celery, CLI, Django, FastAPI, and MLOps starter templates.

Thanks @emberb170d — this PR (#158.python-version) is consolidated into your #159 which already covers #152+#153 combined. Closing #158 to keep #159 as canonical. #162 and #163 remain separate (docs).
