fix: improve bool param validation and preserve None tools

- Fix bool type checking in CommandFilter.validate_and_convert_params
  (was using isinstance(bool_instance, bool) instead of 'bool is bool')
- Preserve tools=None when persona explicitly has no tools
- Add missing provider_wake_prefix in test setup
