Slice 1: Python package scaffolding (prefactor)

#1 — context2html Framework

What to build

Create the context2html/ Python package directory structure with empty modules ready for the three framework seams. This is a pure structural change — no behavior, no new tests yet.

• Create context2html/__init__.py with package metadata
• No runtime dependencies; pyproject.toml already exists
• Existing 376 tests in scripts/test_*.py still load via importlib and pass unmodified
• All existing entry points (validate-report.py, generate-theme-css.py, etc.) continue to work

The goal is to "make the change easy" — lay the package foundation so subsequent slices can import from context2html.registry etc. without needing to restructure the codebase again.

Acceptance criteria

• python -c "import context2html; print(context2html.__version__)" works
• All 376 tests pass: python -m pytest scripts/test_validate_report.py scripts/test_validate_lesson.py scripts/test_generate_theme_css.py -v --tb=short
• Existing entry points (validate-report.py, generate-theme-css.py) still work
• uv pip install -e . succeeds
