feat: animated execution log with truth table + waveform viewer

When the player executes wiring, the panel transitions to a full
execution log showing:
- Animated truth table with rows revealing one by one (flash effect)
- Digital waveform viewer with square wave signals for each port
- Scanning cursor animation during evaluation
- Pulsing glow verdict (pass/fail) after all test cases complete
- Color-coded columns: orange for inputs, blue for outputs
