Replace Cookiecutter with Copier for template generation, gaining support
for template updates (`copier update`) and conditional file generation.
Key changes:
- cookiecutter.json → copier.yml with typed variables and validation
- Template directory restructured to template/ subdirectory
- Hooks replaced with Copier tasks (tasks/post_generate.py)
- Add modular CD pipeline: GitHub Actions or Homelab (GitLab + Portainer)
- VS Code settings (incl. Copilot toggle) generated by post-gen task
Bugs fixed:
- Add [build-system] to template pyproject.toml
- Add __init__.py to template package directory
- Fix GitHub Actions ${{ }} syntax with {% raw %} blocks
- Remove dead Python 2 code, stale .pylintrc, commented prettier block
- Remove dead PIP env vars from Dockerfile, pin uv version
- Remove redundant PLR ruff rule
Test improvements:
- Session-scoped fixture (7s vs regenerating per test)
- New tests for variable rendering, workflow content, CD pipeline variants

- Change [project.optional-dependencies] to [dependency-groups] so `uv sync --dev` actually installs dev dependencies - Add libatomic1 to root Dockerfile for pyright's Node.js binary Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Root CI: test against 3.12, 3.13, 3.14, and 3.x with fail-fast: false - Template CI: test chosen version + 3.x with allow-prereleases - Add 3.14 to copier.yml python_version choices Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
