     * @deprecated This function is deprecated and will be REMOVED in the next major release (v0.2.0).
     *
     * ⚠️ DEVELOPMENT POLICY:
     *   - NO new development or feature additions permitted on this interface
     *   - Only critical bug fixes (security/stability) allowed until removal
     *   - All new code MUST migrate to the polymorphic overload below
     *
     * Replacement: Use the polymorphic overload of this same function name with updated signature
     * Reason: Legacy signature lacks support for dynamic quantization modes.
     * Removal target: v0.2.0 (Q2 2026)
