Scenario 8 – EC-521 → ML-KEM-768 Bulk Re-encryption (Compact JWE)

This scenario performs a non-streaming migration of ciphertext from a classical EC-521 key to a post-quantum ML-KEM-768 key, entirely on the server side (no plaintext exposure):

1. Generate an EC-521 key and encrypt a file (Compact JWE).
2. Generate an ML-KEM-768 key.
3. Re-encrypt the EC ciphertext on the server (EC-521 → ML-KEM-768).
4. Decrypt the new KEM ciphertext.
5. Validate round-trip integrity.

Implementation notes (Java 21+):

• Filesystem operations rely on the Path API.
• UTF-8 encoding is enforced explicitly for deterministic behaviour.
• Temporary artefacts are written under temp_files/.

Thread-safety: this class is stateless and immutable.
