v2.3.2 - Remove Legacy ENABLE_DEVICE_RESPONSE Guards (2026-02-24)

What Changed?

This release removes all ENABLE_DEVICE_RESPONSE conditional compilation guards from the v2 codebase. The main branch is now v2-only, and the unified device response protocol is always active. No behavior changes — the compiled firmware is identical to v2.3.1.

What's New

Main Feature: Unconditional Unified Protocol

What it does: Removes #if ENABLE_DEVICE_RESPONSE / #endif preprocessor blocks from 7 files. The ENABLE_DEVICE_RESPONSE flag was hardcoded to 1 in config.h, making these guards dead code. The legacy #else branch in v2_command_queue.h (containing is_ok and message[512] fields) has also been deleted.

How to use it: No changes required. Build and upload as usual.

task v2:build
task v2:upload
