The README's release and license badges render as invalid on github.com.

• What GitHub shows: fetched through GitHub's image proxy (camo), both badges show release: invalid and license: invalid.
• What shields.io serves: fetched directly, the same URLs render fine. So camo has cached an error response. I don't know what caused the error; most likely a temporary GitHub API failure on the shields side.
• A second problem behind it: the release badge used include_prereleases&sort=semver. Once the cache cleared it would show release: rootfs-v29.9.0-2, because the engine rootfs releases (29.x) sort above the app versions (0.x).

Changes

• Release badge: filter=v*&sort=semver, so only app tags count, and include_prereleases is dropped. It renders release: v0.10.0. The URL change also skips the bad cache entry.
• License badge: now static (badge/license-Apache--2.0). The license never changes, so it doesn't need a GitHub API call that can fail. It renders license: Apache-2.0.

Both new URLs were fetched from shields.io and render as stated. That GitHub shows them correctly can only be seen after merge; I'll check the rendered README then.
