test: add pytest suite — CLI smoke + config/templates/md_to_pdf units

- tests/conftest.py redirects MYTOOLKIT_HOME to a temp dir before imports
  so the module-level Config singleton never touches the real ~/.mytoolkit
- CLI smoke: every registered command answers --help with exit code 0
- unit tests: Config get/set/migrate, templates_registry override/fallback,
  md_to_pdf pure helpers (pandoc-dependent cases skipif-guarded)
- pyproject: dev dependency group (pytest) + pytest config; Makefile: make test
