Subject: [PATCH] fix(examples): correct SSD1306 + big-sound-sensor pin names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

robot-desktop-eyes and the day-30/100-days OLED example wired the
SSD1306 OLED with SDA/SCL/VCC, but the wokwi-ssd1306 element
exposes pinInfo as DATA/CLK/VIN/GND. The mismatched names couldn't
resolve, so all three wire endpoints fell back to (0,0) of the
component and visually attached to the corner instead of the pins.

Same class of bug on the wokwi-big-sound-sensor in
robot-desktop-eyes: the element has AOUT/DOUT (no plain OUT). The
sketch uses digitalRead(SOUND_PIN), so route to DOUT.

The COMPONENT_PIN_ALIASES map in wokwiZip.ts only normalises on
.zip import — static examples have to use the real pinInfo names.
