v1.2.1

This is v1.2.1 of the Hyperdrive daemon. This is meant to be used by the Hyperdrive service.

This includes some client updates and bug fixes. It also removes Holesky from the list of default networks.

This is required for Nimbus users that haven't manually updated to v25.4.1 manually due to a high-priority bugfix.

All users are required to update clients to Pectra-compatible versions on Mainnet before epoch 364032, May 7 2025 - 10:05:11 AM UTC. For Hyperdrive, this is v1.2.0 or higher.
