Lineax: JAX-native Linear Solvers

Lineax provides high-performance, JIT-compilable, and differentiable linear solvers for systems of the form Ax=b, built on JAX and designed to integrate seamlessly with Equinox. It enables defining custom linear operators and choosing various direct or iterative solvers. The current version is 0.1.0, indicating an early stage of development, with a release cadence that tends to follow updates in the broader JAX and Equinox ecosystem.
