Crate get_dir_hash 

Deterministic directory hashing with simple glob ignores.

Design:

• Build a file list by walking root and filtering via globset.
• Sort files by normalized relative path to guarantee stable order.
• For each file: stream its content into an inner blake3 hasher, then feed the outer hasher with record-framed data: b“F\0“ + path + b“\0“ + content_digest + [metadata?].
• Finally, return the outer digest as lowercase hex.

This crate intentionally keeps ignore semantics minimal (no ! negations).
