I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

๐ Info: API keys still read from env var, not KV
AGENTS.md requires runtime secrets be read from a KV/credential registry and names get_configured_api_keys reading CODEC_CARVER_API_KEYS as a known deviation to migrate. This PR hardens the auth path but leaves the env-var read in place. Pre-existing and unchanged here.

retrieve runtime API keys from the credential registry/KV instead of reading
CODEC_CARVER_API_KEYS directly from os.environ. Restrict the environment
variable to KV bootstrap, and update test fixtures to seed and read keys through
the same credential store.
