/send-app — Flash the latest demo to Pico W

Runs bundle exec rake pico:send_app from the project root.

This task:

1. Concatenates examples/road_to_rubykaigi/*.rb into tmp/road_to_rubykaigi.rb (single module RoadToRubykaigi wrapper)
2. Bundles with examples/accelerometer.rb into tmp/app_bundled.rb
3. Sends to /home/app.mrb on the connected Pico W via bin/send_file.rb --mrb (auto-detects /dev/cu.usbmodem*)

Prerequisites

• PICORBC env var set to the picorbc binary path (typically exported in shell rc; required by bin/send_file.rb)
• Pico W connected over USB with picoruby firmware running shell (not blocked in the BLE loop)

Failure modes

• no ACK — Pico is busy emitting puts on USB CDC. Reboot the Pico and press s during the Press 's' to skip running /etc/init.d/r2p2 window
• No /dev/cu.usbmodem* — no Pico connected, or different device path
• picorbc: command not found — PICORBC env not set

If the command fails, report the stderr to the user and suggest the matching remedy above. Do not retry automatically.
