v0.13.1

• Fix the prebuilt container install, which failed on every platform: the Dockerfile copies install-browser-policy.sh out of the embedded build context and that file was never embedded, so the default install path died on a missing file while --from-source kept working
• Report what the builder actually said when an image build fails, instead of asserting an unchecked cause; the source-build routes are named only when the release download is what failed, rather than on every failure regardless of reason
• Hand the data volume to the image's own account before first start on the Apple runtime, where a named volume is mounted root-owned and the non-root host could not create its state directory
• Read container state from Apple's inspect shape (status.state) as well as Docker's (State.Running), and list with ls rather than a ps subcommand Apple does not have; between them every container on that runtime read as stopped and a healthy host was reported as having exited
• Update the pinned camoufox backend from v152.0.4-beta.28 to v152.0.4-beta.29
