Subject: [PATCH] esp-idf: export ESP_IDF_VERSION from version.txt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Derived as major.minor, matching ESP-IDF's own tools/idf_tools.py, which
matches '^v([0-9]+\.[0-9]+).*' against version.txt. Components such as
esp_wifi_remote — the Wi-Fi path for the ESP32-P4 — compare against that
two-part form, so emitting the patch level would not help them.

Fixes #124.
