bearer-token source precedences (AWS SM, JSON file/env, single token).
New "Build Variants" section explaining default vs aws builds and
their release-artifact naming. New "AWS Secrets Manager" section
covering env var, secret payload format, IAM role credential
discovery, and the hard error for feature-less builds.
