Pull request overview
This PR updates the ESP-IDF camera-streamer example to use the newer managed esp32-camera component and adjusts the RTSP streaming loop and system configuration to improve throughput and resiliency.
Changes:
- Migrates the camera dependency from a git submodule to a managed ESP-IDF component and updates the dependency lockfile.
- Updates RTSP streaming behavior (session-aware capture pacing, backoff, and WiFi power-save disable) and adds heap/task monitoring hooks.
- Tweaks default sdkconfig and partitions (PSRAM/WiFi/LWIP tuning; LittleFS partition subtype).
