 /**
- * Reads a feature.manifest.ts file and extracts the manifest's `name` field
- * and `requiredCores` array via regex. Returns null if the file does not
- * exist or does not match the expected literal `as const` manifest shape.
- *
- * The repo's convention is that every feature.manifest.ts uses defineFeature
- * with literal `as const` syntax — this is enforced by the type-system
- * design (defineFeature has `<const M>` to preserve literal types). The
- * regex extraction is therefore safe; the AST path is overkill.
+ * Reads a feature.manifest.ts and returns { name, requiredCores }.
+ * Backed by the AST parser from _manifest-ast.js — no longer uses regex.
  *
  * Returns: { name: string, requiredCores: string[] } | null
