fix(test): avoid separate mkdir cache entries in output-cache-test

On Windows, `&&`-chained commands become separate cache entries. The
`vtt mkdir -p dist` sub-command's fspy-inferred input is the `dist`
directory itself — when the test deletes `dist`, the next run detects
`dist` was removed and reports a cache miss for that sub-command.

Fix by making `vtt write-file` create parent directories automatically,
then removing the `mkdir` commands from test fixtures.
