/**
 * Resolves schema extensions by deep-merging base schemas into extension schemas.
 *
 * When a schema has `extends_schema_name` set, the base schema is looked up
 * from the already-fetched schemas and deep-merged with the extension.
 * The extension wins on conflict.
 *
 * Design constraints:
 * - Single-level only: a base schema must not itself be an extension
 * - Same tenant only: enforced at DB level
 * - `extends_schema_version`: if set, matches against `schema_version`;
 *   if null, the base's `version_current` entry is used (already in the list)
