fix(release): close the first review of the production release path

Host rehearsal no longer needs Node on the production machine, and a failed cleanup now stops with the rehearsal database name. Docs-only staging heads no longer block rollback. Tests no longer hardcode Windows paths, and a trailing slash on the production site still refuses the test code.

pytest 12 passed; tsc exit 0; lint 0 errors; identity tests 9 passed, 0 cancelled. test:db was not run.
