Before this PR, the following test passed:
def test_pyscript_hello(self):
self.pyscript_run(
"""
<script type="py">
raise Exception("hello")
</script>
""")
What happens is that we intercept the Python exception and display a nice banner on the DOM, but the test itself passes. This is error prone: if we have Python exceptions on the page, the test should fail by default, and we should have a way to silence it in case those exceptions are expected.
This PR treats Python errors as we treat JS errors: unhandled exceptions cause the test to fail, but you can silence them by calling self.check_py_errors(), exactly as you can call self.check_js_errors().
This PR adds support for optionally running pyodide in a web worker:
- add a new option config.execution_thread, which can be `main` or `worker`. The default is `main`
- improve the test machinery so that we run all tests twice, once for `main` and once for `worker`
- add a new esbuild target which builds the code for the worker
The support for workers is not complete and many features are still missing: there are 71 tests which are marked as `@skip_worker`, but we can fix them in subsequent PRs.
The vast majority of tests fail because js.document is unavailable: for it to run transparently, we need the "auto-syncify" feature of synclink.

In the future this should help us leak fewer names into the pyscript
namespace.
Rather than assigning to the pyscript module from JavaScript, we
mount a separate private JS module with the extra names needed by
PyScript. I moved a bit more interpeter intialization into
remote_interpreter.
I added a deprecation warning for `pyscript.js`: the proper way to
access `js` is `import js`.
