The tooling merge took its own install.sh and install.ps1, which only
moved the pin, and dropped the bootstrap checks of the installer
batch. The ported checksum test calls the TypeScript node helper of
its merged module, and the retrodeck excerpt follows the run.
The site test modules were cut by review pass (test_site_r2_css to test_site_r5_wiki): the passes of one subject become one module, and the modules that stood alone take the name of what they hold. The installer test classes named after a review take the name of what they test. One test left --manifest set for the tests after it, which the new order showed: it now resets the sources.
