Exercise 08: SystemStartup Package Scaffold

This exercise starts a reusable SystemStartup package that is intended to be shared by future exercises and field firmware.

Current package responsibilities:

1. Initialize OLED and show boot/status messages.
2. Initialize SD startup watcher.
3. Keep SD monitoring active in loop() with a single call.

Current integration pattern:

#include "SystemStartup.h"

static SystemStartup g_systemStartup(Serial);

void setup() {
  Serial.begin(115200);
  g_systemStartup.begin();
}

void loop() {
  g_systemStartup.update();
  delay(10);
}

This is the foundation for adding more startup subsystems (RTC sync/check, etc.) behind the same begin()/update() API.
