release: v0.5.2 — restore JAX 0.11 compatibility

[chaoming0625]

Summary

Maintenance release bumping the version to 0.5.2. The public API is unchanged, so this is a drop-in upgrade from 0.5.1.

The release centers on restoring compatibility with JAX 0.11: the is_constant_dim helper used by saiunit.math.einsum was removed from the public jax.core namespace in JAX 0.11, and is now sourced through the version-aware saiunit._compatible_import shim.

Changes

• Restore einsum on JAX 0.11 — import is_constant_dim via _compatible_import (public jax.core on JAX < 0.10, private jax._src.core on JAX ≥ 0.10) and route _einops.py through the shim instead of jax.core.is_constant_dim directly (fix: source is_constant_dim from jax._src.core on JAX>=0.11 #135).
• Expose is_constant_dim from _compatible_import.__all__ with a require_jax stub for JAX-less installs (fix: source is_constant_dim from jax._src.core on JAX>=0.11 #135).
• Fix the mypy type-check gate — annotate the version-guarded concrete_or_error / is_constant_dim fallback imports and align the compatibility export test with __all__ (test: align _compatible_import EXPORTS with __all__ (fix CI) #138).
• CI — bump actions/checkout 6→7 (⬆️ Bump actions/checkout from 6 to 7 #134) and actions/setup-python 6→7 (⬆️ Bump actions/setup-python from 6 to 7 #136).

Verification

• mypy saiunit/ exits 0.
• import saiunit; saiunit.__version__ == "0.5.2".

See changelog.md for the full Version 0.5.2 notes.
