[FEATURE]: extends the Merkle proof system by adding portable proof export and standalone

[aniket866]

Feature and its Use Cases

Problem

Currently, Merkle proofs can only be generated and verified in memory during runtime.

There is no way to:

• Save a generated proof

• Share a proof with others

• Load a proof later for verification

• Perform standalone verification using a stored proof file

• This limits practical usage for large dataset distribution and independent auditing.

Additional Context

Impact

Users cannot verify dataset chunks without regenerating proofs, making the system less flexible and less suitable for real-world verification workflows.
