/**
 * Semantic Release Configuration
 *
 * Branch-aware config:
 * - dev branch: Uses dev release configuration (prerelease)
 * - main branch: Uses production release configuration (stable, npm @latest)
 *
 * RC soak window for Docker mutable tags is handled entirely in docker-release.yml:
 * every release event publishes the immutable :<ver> Docker tag immediately;
 * mutable :latest/:MAJOR/:MINOR tags require an explicit operator action via
 * `gh workflow run promote-release.yml -f tag=vX.Y.Z` (workflow_dispatch).
 * npm @latest is always set immediately on stable release — no rc soak needed.
