Templatize `str(handle h)` with SFINAE to exclude types derived from `object`, resolving ambiguity with `str(const object&)` when calling `py::str()` on types like `kwargs`, `dict`, etc. The template now only accepts `handle` or `PyObject*`, while all `object`-derived types use the `str(const object&)` overload.
- Install multiple-interpreter test modules into wheel (CMakeLists.txt) The mod_per_interpreter_gil, mod_shared_interpreter_gil, and mod_per_interpreter_gil_with_singleton modules were being built but not installed into the wheel when using scikit-build-core. - Pin numpy 2.4.0 for Python 3.14 CI tests (requirements.txt) NumPy 2.4.0 is the first version with official Python 3.14 wheels. - Add IOS platform constant to tests/env.py - Skip subinterpreter tests on iOS (test_multiple_interpreters.py) Subinterpreters are not supported in the iOS simulator environment. - Enable pytest timeout of 120s for CIBW tests (pyproject.toml) Provides a safety net to catch hanging tests before CI job timeout. - Disable pytest-timeout for Pyodide (no signal.setitimer) Pyodide runs in WebAssembly without POSIX signals. - Add -v flag for verbose pytest output in CIBW tests

Description
Fixes #5938
Templatize
str(handle h)with SFINAE to exclude types derived fromobject, resolving ambiguity withstr(const object&)when callingpy::str()on types likekwargs,dict, etc.The template now only accepts
handleorPyObject*, while allobject-derived types use thestr(const object&)overload.Piggy-backed: CIBW fixes (failing on master) commit 0e062f2
Suggested changelog entry:
str(handle)constructor when called withobject-derived types likekwargsordict. The constructor is now templatized with SFINAE to excludeobject-derived types, which use thestr(const object&)overload instead.
