test(history): jsdom/renderHook lane + useBackToExit back-ladder tests

Browse Source

First DOM-capable vitest lane for the repo: default env stays node (pure lib helpers), a test opts
into jsdom per-file with a // @vitest-environment jsdom docblock; plugin-react wired for JSX/hook tests.
Adds jsdom + @testing-library/react devDeps and 3 back-ladder tests (LIFO peel, stacks over

no dependency on jsdom's async back(). Closes the deferred R2 component-test gap (useBackToExit).
