[async worker] include atproto workspace in image

[ayubun]

Description

Include the existing example_atproto_plugins workspace member in the async-worker image dependency layer. The root lockfile was already current; the image build failed because its partial workspace omitted this member before uv sync --locked.

The change mirrors the stable-worker image by staging the member metadata and minimal package before dependency installation, then overlaying the real source afterward. example_atproto_rules remains out of scope because it is not a workspace member and does not affect locked dependency resolution.

• copy example_atproto_plugins/pyproject.toml before locked workspace sync
• create its real src/atproto_plugin package shape in the cached dependency layer
