nanobind: upgrade to version 2.11.0

[agarny]

Fixes #533.

[Copilot]

Pull request overview

Upgrades the vendored nanobind submodule to v2.11.0 (fixing #533), including ABI/runtime changes (module state, vectorcall/immutability), expanded ndarray framework support, and corresponding test/stub/doc updates.

Changes:

• Bump nanobind version to 2.11.0, update ABI internals (ABI v18), and raise minimum supported Python to 3.9+ across build/config/docs.
• Improve/extend stub generation (performance, enum edge cases, module/class prefix/suffix patterns, --exclude-values) and update reference stubs/tests accordingly.
• Add/adjust tests for new runtime/typing/ndarray behavior (JAX/TensorFlow/array-api, specialization, threading races, never-destruct, etc.).
