Pull request overview

This PR expands unit test coverage in sshlib and refactors a few previously-private helpers into reusable internal utilities to enable more direct testing of encoding/constraint logic.

Changes:

• Add EqualsVerifier-based equals/hashCode tests for AuthPublicKey, BindingEntry, and SignedDataComponents.
• Add focused tests for extracting the algorithm name from an SSH public key blob, and move that logic into an internal helper.
• Refactor agent helper logic (buildAgentMessage, destination-constraint evaluation, and related value types) into internal top-level declarations and add boundary/roundtrip tests for message length encoding.
