"""Tests for the post_setup install-state gate in `_toolset_needs_configuration_prompt`.

Regression coverage for the cua-driver silent-no-op bug (issue #22737).

When a no-key provider's only install side-effect is a `post_setup` hook
(cua-driver, etc.), the gate function used to fall through to the
`_toolset_has_keys` catch-all, which returned True for any provider with
empty `env_vars` — causing `hermes tools` to write the toolset to config
and exit `✓ Saved` without ever invoking the post_setup install. These
tests pin the new predicate-aware behaviour so the regression doesn't
sneak back in.
