aphrodite-engine/aphrodite-engine redirects to dphnAI/sonar

Evidence for the Aphrodite -> Sonar rename: HTTP 301 to https://github.com/dphnAI/sonar, and the Sonar README still installs and serves under the `aphrodite` command name. The aphrodite-engine GitHub org now holds only .github, aphrodite-loadbalancer and aphrodite-jax. NOTE: the widely repeated claim that Aphrodite was 'absorbed into SGLang' is NOT supported by what could be checked: a commit search for 'aphrodite' in sgl-project/sglang returns 0 commits (only 4 issues). Treat the absorption claim as unverified.
