Prefix private modules with underscore

What was changed

Prefix private modules with _

Why?

Discourages user use (especially since many are exposed via the parent module anyways)

Checklist

Maybe I missed something, but should we mark the sandbox module as restricted? Looking at the readme we a user could use classes in _restrictions.py

my_restrictions = dataclasses.replace(
    SandboxRestrictions.default,
    passthrough_modules=SandboxRestrictions.passthrough_modules_default | SandboxMatcher(access={"pydantic"}),
)
my_worker = Worker(..., runner=SandboxedWorkflowRunner(restrictions=my_restrictions))

@Quinn-With-Two-Ns - No, https://python.temporal.io/temporalio.worker.workflow_sandbox.html is intentionally public (yet unstable) API. I re-export the things I want public from _restrictions.py to the parent module.

Thanks I missed the re-export
