chore(deps): consolidate Python dependency range widening for release-v1

[MilesCranmerBot]

Consolidates multiple dependabot Python dependency bumps for the release-v1 branch.

Changes:

• juliacall >=0.9.24,<0.9.27 → >=0.9.24,<0.9.36
• beartype >=0.19,<0.22 → >=0.19,<0.23
• jax[cpu] >=0.4,<0.6 → >=0.4,<0.7
• mypy >=1,<2 → >=1,<3
• pytest-cov >=5,<7 → >=5,<8

Closes #1228
Closes #1230
Closes #1232
Closes #1234
Closes #1235

@MilesCranmerBot can you check if these dependency upper bounds are actually used?

[MilesCranmerBot]

Here's the analysis of each upper bound and whether it's actually exercised:

Package	New bound	Latest on PyPI	Used in codebase?	Verdict
juliacall	<0.9.36	0.9.35	✅ Core dep — pysr/julia_import.py, tests	⚠️ Barely includes the latest release. Next version (0.9.36) will be excluded.
beartype	<0.23	0.22.9	✅ Optional runtime — pysr/__init__.py (gated on PYSR_USE_BEARTYPE=1); CI has a dedicated beartype job	⚠️ Same — barely includes latest.
jax[cpu]	<0.7	0.10.2	✅ pysr/export_jax.py, test_jax.py, CI runs jax tests	❌ Too restrictive. JAX is already at 0.10.2; this bound excludes 0.7–0.10.x.
mypy	<3	2.1.0	✅ CI runs mypy --install-types and mypy --ignore-missing-imports	✅ Fine — includes all current versions.
pytest-cov	<8	7.1.0	⚠️ Not directly used. CI uses the coverage package directly (coverage run -m pysr test ...). No pytest config references --cov. The separate coverage>=7,<8 dep is what CI actually uses.	✅ Bound is fine, but the package itself may be dead weight.

@MilesCranmerBot could you please adjust to include the newer jax versions please
