- Added 'make docs', 'make docs-preview', and 'make audit' targets to Makefile for easier local development.
- Added comprehensive README.md to the vscode-ext workbench extension.
- Refactored test_engine.py to dynamically import calibration constants rather than hardcoding physics assumptions, ensuring tests don't break if base parameters are tuned.
- Fixed a registry path alias in philosophy.qmd caught by the doc drift linter.
The \n in the printf format string was split into a literal newline,
causing a "missing separator" syntax error when running `make help`.
