Secp256k1 Keypair Management for Spark Wallet

This module defines the trait for managing secp256k1 keypairs in the Spark wallet. Secp256k1 is the elliptic curve used by Bitcoin, and this module provides methods for generating, storing, retrieving, and manipulating secp256k1 keypairs.

The Spark wallet uses several types of keypairs:

• Identity keypairs for wallet identification and authentication
• Leaf keypairs for individual UTXOs (leaves) in the wallet
• Ephemeral keypairs for one-time operations like key exchange

Proper keypair management is critical to the security of the wallet, as these keys control access to funds and provide cryptographic identity.
