feat(macos): spike rootless Docker inside bottles
Add an opt-in docker_access path that layers rootless Docker tooling onto the selected agent image, starts the daemon only after registration, and retains the existing outer network and capability boundary. Include fail-closed bootstrap checks plus a live-Mac Compose/security acceptance test.\n\nRefs #392.

"""Live-Mac acceptance spike for guest-local rootless Docker (issue #392).
Run explicitly on an Apple Silicon/macOS 26 host:
BOT_BOTTLE_ROOTLESS_DOCKER_SPIKE=1 \
python3 -m unittest tests.integration.test_macos_rootless_docker_spike -v
The opt-in is deliberate: ordinary Linux CI cannot execute Apple Container.
