v0.44.0

[0.44.0] - 2025-08-28

This small release primarily fixes a few issues, but also adds the code for a prelease of subxt-historic, a new crate (at the moment) for working with historic blocks and state. Future releases will aim to stabilize this crate to the level of other subxt crates or otherwise merge the logic into subxt itself.

This is a minor version bump because, in theory at least, adding the Clone bound to block headers in (#2047) is a breaking change, although I think it is unlikely that this will impact any users.

• Add prerelease subxt-historic crate for accessing historic (non head-of-chain) blocks (#2040)
