Add Python 3.13–3.15 and free-threading wheel support (#2314)

Update Python bindings to support Python 3.10–3.15, including free-threaded
3.14t and 3.15t builds.

Switch the wheel build to nanobind 3 split mode (`nanobind-backend>=1.0`),
which moves Python-version-specific runtime internals into `nanobind-backend`
so that stable ABI wheels work starting from Python 3.10 instead of 3.12 and
support PEP 803 (`abi3t`) on Python 3.15t+. This reduces the wheel matrix to
three wheels per platform architecture (`cp310-abi3`, `cp314-cp314t`, and
`cp315-abi3t`), and the `cp310-abi3` and `cp315-abi3t` wheels should be
forward-compatible with future Python releases.
