Generalizes the LED's burnout to passive parts via a centralized monitor that
watches the live electrical solve. When a part is stressed past its rating for
a sustained moment it's marked "destroyed": the canvas renders it charred with a
smoke badge and a fault is logged to the output console. Clears on Reset.
Follows the Fritzing-simulator precedent (smoke-on-component) wrapped in a
first-order thermal delay so a brief inrush spike doesn't destroy a part — only
sustained overload (or a catastrophic >=3x overload, instant) does.
- runtimeBurnout.ts: pure stress (resistor power, cap voltage / reverse) + a
thermal-delay burn decision, plus a monitor subscribed to the electrical +
simulator stores. Resistor burns past 2x rated (the verifier already warns at
1x for intentional teaching over-power); a cap bursts over its voltage rating
or on reverse polarity.
- useSimulatorStore: burntComponents set + mark/clear actions; cleared on
Reset / restartParts.
- DynamicComponent + SimulatorCanvas.css: charred filter + smoke badge.
Tests: thermal-delay decision (instant / sustained / spike / cooldown) + stress
computation (resistor power, cap over-voltage, reverse, unwired -> null).
