## Summary * **What is the goal of this PR?** Fixes #199 - Device falls asleep during WiFi file transfer after 10 minutes of inactivity, disconnecting the web server. * **What changes are included?** - Add `preventAutoSleep()` virtual method to `Activity` base class - Modify main loop to reset inactivity timer when `preventAutoSleep()` returns true - Override `preventAutoSleep()` in `CrossPointWebServerActivity` (returns true when web server running) - Override `preventAutoSleep()` in `OtaUpdateActivity` (returns true during update check/download) ## Additional Context * The existing `skipLoopDelay()` method controls loop timing (yield vs delay) for HTTP responsiveness. The new `preventAutoSleep()` method is semantically separate - it explicitly signals that an activity should keep the device awake. * `CrossPointWebServerActivity` uses both methods: `skipLoopDelay()` for responsive HTTP handling, `preventAutoSleep()` for staying awake. * `OtaUpdateActivity` only needs `preventAutoSleep()` since the OTA library handles HTTP internally.
