## Title

    Proposed fix: [JAX >=0.6.0] AttributeError 'jax.tree_map was removed in JAX v0.6.0: use jax.tree.map (jax v0.4.25 or newer) or jax.tree_util.tree_map (any JAX version).'

## Body

    Recommended action: Use jax.tree.map (>=0.4.25) or jax.tree_util.tree_map (all versions); for jax.random.KeyArray use jax.Array.
    
    Option: Use jax.tree.map (>=0.4.25) or jax.tree_util.tree_map (all versions) [evidence: official_recommended_action]
    Applies when: jax>=0.6.0 (deprecated since 0.4.26-era); jax.random.KeyArray/PRNGKeyArray removed in 0.4.24
    Steps:
    1. Replace jax.tree_map(f, t) with jax.tree_util.tree_map(f, t) (portable) or jax.tree.map
    2. Replace jax.random.KeyArray annotations with jax.Array
    Expected: Import/call succeeds on the new version
