z3 already builds under Pyodide, but via `pyodide build` the resulting wheel is tagged `emscripten_<pyodide-version>_wasm32` and only usable as a CI artifact. PEP 783 introduced the portable `pyemscripten_<date>_wasm32` tag that PyPI accepts and micropip can install at runtime. This makes z3 produce that wheel via `cibuildwheel --platform pyodide`. Changes: * setup.py: for the emscripten target, use the wheel platform tag that pyodide-build supplies verbatim via _PYTHON_HOST_PLATFORM (e.g. `pyemscripten_2026_0_wasm32`) instead of reconstructing an `emscripten_*` tag, falling back to the old behaviour when that env var is absent. * setup.py / CMakeLists.txt / pyproject.toml: switch the Pyodide build from JS-based exceptions (`-fexceptions`, `-sDISABLE_EXCEPTION_CATCHING=0`) to native wasm exception handling (`-fwasm-exceptions -sSUPPORT_LONGJMP=wasm`), matching the ABI of the Pyodide 314 / emscripten 5 main module. With the old flags libz3.so imports `invoke_*` trampolines the runtime no longer provides, so the wheel builds but the first Z3 call fails at runtime with "Dynamic linking error: cannot resolve symbol invoke_vi". * pyproject.toml: add [tool.cibuildwheel] / [tool.pyodide.build] config so `cibuildwheel --platform pyodide` builds and tests the wheel. * add .github/workflows/pyodide-pypi.yml building the wheel with cibuildwheel and publishing it to PyPI (trusted publishing) on tags. The existing pyodide.yml artifact build is left unchanged. Verified with cibuildwheel 4.1.0 / pyodide-build 0.35.0 / emscripten 5.0.3: the resulting z3_solver-4.17.0.0-py3-none-pyemscripten_2026_0_wasm32.whl passes z3test.py in the Pyodide runtime and solves SMT problems both under node and in a browser via micropip.
