"""
Which files count when deciding a sketch uses WiFi (issue #260).

The Arduino path used to read only the entry sketch while the pure-IDF path
read every file, and that asymmetry was not cosmetic: a "no WiFi" verdict made
the QEMU worker leave the radio out of the machine, so the firmware's first
touch of the MAC panicked with LoadStorePIFAddrError instead of merely failing
to connect. A header that includes WiFi.h is as much a WiFi project as an .ino
that does.
