validate_directory_as_bids
==================================================

.. py:function:: petpal.utils.bids_utils.validate_directory_as_bids(project_path: str) -> bool

   Validate whether all files in a given directory and its subdirectories (excluding specified ones)
   conform to the Brain Imaging Data Structure (BIDS) standard.

   :param project_path: The root directory of the project to validate.
   :type project_path: str

   :returns: *bool* -- True if all files in the directory conform to the BIDS standard, False if any do not.

   :raises FileNotFoundError: If the provided project_path does not exist or is inaccessible.

   .. rubric:: Notes

   Excludes directories typically not needed for BIDS validation, such as 'code', 'derivatives',
   'sourcedata', '.git', and 'stimuli'. Also skips directories starting with 'sub-' to focus on top-level structure.
