This release introduces kuber-hydra, a dedicated module that adds full Hydra head
support to Kuber. The new module exposes a set of command and query APIs for
committing, decommitting, closing, fan‑out, contesting, and querying the state of a
Hydra head, along with a transaction‑builder helper and APIs.

Note : kuber-hydra executable additionally exposes all layer1 endpoints making it versatile for both hydra and l1 interaction.
