Implement idempotent UUID generation based on content and website ver…

Description of what has changed

Changed the UUID generation logic to use CONTENT_VERSION and WEBSITE_VERSION as seeds for idempotent UUID creation. This ensures consistent UUIDs for the same content and website versions, optimizing storage usage and preventing the creation of redundant IndexedDB tables.

Closes #455.

Testing

UUID idempotence was tested with the following script:

import hashlib

def generate_uuid_from_seeds(content_version, website_version):
    """
    Generate a UUID based on the given content_version and website_version.

    Args:
    - content_version (str): Semantic version of the content without a leading 'v'.
    - website_version (str): Semantic version of the website with a leading 'v'.

    Returns:
    - str: A UUID generated based on the two versions.
    """
    # Combine and hash the values
    seed = f"{content_version}-{website_version}".encode('utf-8')
    hashed_seed = hashlib.md5(seed).hexdigest()

    # Convert the first 32 characters of the hash to a UUID format
    return '-'.join([hashed_seed[i:i+length] for i, length in zip([0, 8, 12, 16, 20], [8, 4, 4, 4, 12])])

def test_uuid_idempotency():
    """
    Test the idempotency of the UUID generation.
    """
    test_pairs = [
        ("4.0.4", "v13.1"),
        ("4.0.5", "v13.2"),
        ("5.0.0", "v14.0")
    ]

    for content, website in test_pairs:
        first_uuid = generate_uuid_from_seeds(content, website)
        second_uuid = generate_uuid_from_seeds(content, website)

        assert first_uuid == second_uuid, f"UUIDs for {content}-{website} are not idempotent."
        print(f"UUID for {content}-{website}: {first_uuid}")

if __name__ == "__main__":
    test_uuid_idempotency()

Output:

❯ python3 test_uuid.py
