- Replace ProtoSize::varint() call for message_type with inline ternary using named constants, avoiding the noinline varint_slow call overhead in the write_protobuf_messages loop (-32 bytes on ESP8266 Xtensa). - Add named varint threshold constants (VARINT_MAX_1_BYTE, etc.) to ProtoSize class, used by both varint() and varint_wide(). - Devirtualize write_protobuf_packet by moving it to the base class as a non-virtual inline method. The plaintext and noise implementations only differed in footer handling, which is now unified via a conditional resize based on frame_footer_size_. This eliminates one vtable slot and allows the compiler to fully inline the thin wrapper into callers (-192 bytes total flash on ESP8266). - Include proto.h from api_frame_helper.h (no circular dependency) to support the inline definition, replacing the forward declaration of ProtoWriteBuffer.
