+CI installs requirements-dev.txt for all ports, but on Espressif builds we must
+also apply the matching ESP-IDF constraints file so pip does not upgrade shared
+packages (for example click) beyond what ESP-IDF allows. This script derives the
+active ESP-IDF major.minor version from version.cmake and exports the exact
+constraints file path into GITHUB_ENV for later install steps.
