fix(hindsight): add missing get_hermes_home import

Import hermes_constants.get_hermes_home at module level so it is
available in _start_daemon() when local mode starts the embedded
daemon. Previously the import was only inside _load_config(), causing
NameError when _start_daemon() referenced get_hermes_home().

Fixes #5993
