description	Compile Button2 examples across Arduino platforms using arduino-cli and PlatformIO. Pass a platform name (esp8266, esp32, nano, all) or leave blank to compile all.

Compile Button2 examples to verify they build cleanly across target platforms.

Parse $ARGUMENTS:

• If a specific platform is named (esp8266, esp32, nano), run pio run -e <matching env> for that platform
• If "examples" or nothing is given, run ./test/compile_examples.sh to compile all examples across all platforms
• If a specific example name is given, find the matching .ino file under examples/ and compile it with arduino-cli compile for all three cores (esp8266:esp8266:d1_mini, esp32:esp32:m5stack_core2, arduino:avr:nano)

Report any compiler errors clearly, quoting the relevant error lines. If compilation is clean, confirm which platforms and examples passed.
