Harden Sphinx autodoc imports to include full API

[Copilot]

GitHub Actions autodoc skipped large parts of the API due to import-time failures (missing deps, side-effectful modules like main/playground), leading to incomplete docs.

• Autodoc safety: Allow village.main to import in headless/docs environments by not raising on os.nice permission errors.
• Side-effect isolation: Guard the playground latency benchmark so it only runs under __main__, keeping autodoc/import harmless.
• Doc build hygiene: Deduplicate picamera2 in autodoc_mock_imports to avoid redundant mocks.

Example:

if __name__ == "__main__":
    mybpod = BpodWithLatencyTest()
    measure_softcode_latency(mybpod, 200)

Original prompt

I am running sphinxs autodocs to generate the documentation for the API of this repo. I can run it locally with no problem, but the github actions that I am using is not documenting the whole thing. These are some of the errors I am seeing. I want you to identify the problem:

Pull request overview

This PR addresses Sphinx autodoc import failures in GitHub Actions by making several key improvements to allow safe module imports during documentation builds.

Key changes:

• Modified village/main.py to allow imports when os.nice() fails due to permission errors in restricted environments
• Added __main__ guard in village/scripts/playground.py to prevent benchmark execution during imports
• Fixed docs/source/conf.py by removing duplicate picamera2 entry and eliminating a duplicate autodoc_mock_imports assignment that was overwriting the comprehensive mock imports list

Reviewed changes
