    * Implements Protocol Buffer encoding size calculation according to:

    *
    * Key features:
+   * - Object-based approach reduces flash usage by eliminating parameter passing
    * - Early-return optimization for zero/default values
-   * - Direct total_size updates to avoid unnecessary additions
+   * - Static varint methods for external callers
    * - Specialized handling for different field types according to protobuf spec
-   * - Templated helpers for repeated fields and messages
