Pull request overview

Adds Account Abstraction canonical v0.7 support to NuCypher core signature request tooling (and corresponding language bindings), along with small CI / lint cleanup and version bumps to publish an updated dev build for SDK consumers.

Changes:

• Add AAVersion::V07 and implement v0.7 hashing/ABI-encoding for PackedUserOperation (non–EIP-712 signing path).
• Make PackedUserOperation::to_eip712_struct fallible and error for v0.7; propagate this through the Python bindings.
• Bump package versions across Rust/WASM/Python and adjust CI Node matrix.

to_v07_hash reparses ENTRYPOINT_V07 from a string on every call and uses expect(...), which can panic inside a library API if the constant is ever changed/invalid. Consider parsing the entry point once (e.g., a const/lazy_static/once_cell H160/Address) and using that value here to avoid repeated work and eliminate the panic path.
