libtpu only ships Linux wheels, so the hard jax[tpu] dependency made the package uninstallable on macOS and installed an unneeded TPU runtime on other non-TPU platforms. Keep jax[tpu] on Linux and depend on plain jax elsewhere, with the same version constraints. Fixes google#2047

Fixes #2047.
Implements option 2 as requested in #2047 (comment): keep
jax[tpu]as a hard dependency on Linux (so downstream libraries like qwix, metrax, and orbax that reinstall JAX keep working in the nightly regression), and depend on plainjaxon other platforms where libtpu ships no wheels.Version constraints are unchanged on both branches (
>=0.6.0,!=0.7.2,<0.11.1). On Linux (including TPU hosts and CI) the resolved dependency set is identical to before, so this is fully backward-compatible; on macOS the package becomes installable, and other non-Linux platforms no longer pull in the TPU runtime.
