Release v1.43.0

Good day Lodestar operators! We've just released v1.43.0 and recommend users upgrade for the latest features and best performance. This release has an important fix or self rate-limiting so that we are better peers, and thus have better peering and syncing. We also fixed a bug in block-import performance, as well as another substantial wave of ePBS / Gloas progress.

Operational Note: Internal tooling moved to pnpm v11. There will be no action required for operators running via Docker, however if you are building from source you will need to update your version of pnpm.
