Pull request overview

This PR repackages the upstream 78/xiaozhi-esp32 project into a course/assignment-oriented ESP32-S3 (OttoRobot) variant intended to build on ESP-IDF v5.3.2, primarily by downgrading component dependencies and stubbing/removing features that rely on newer IDF APIs or the esp_video stack.

Changes:

• Downgrade main/idf_component.yml dependency constraints for ESP-IDF 5.3.x compatibility and remove espressif/esp_video.
• Remove/disable esp_video-based camera paths for ESP32-S3; stub OttoRobot camera init and WebSocket control server.
• Replace the root README.md with a course-focused Chinese build guide and add README_ORIGINAL.md + DEPENDENCY_CHANGES.txt documentation.

File	Description
README.md	Replaced upstream README with ESP-IDF 5.3.2 / OttoRobot course-oriented instructions and limitations.
README_ORIGINAL.md	Added a backup copy of the upstream README content.
main/idf_component.yml	Downgraded component versions and IDF requirement; removed esp_video dependency.
main/display/lvgl_display/jpg/image_to_jpeg.h	Avoid Linux V4L2 header on non-P4; defines V4L2 pixel formats for other targets.
main/CMakeLists.txt	Stops compiling esp_video.cc on ESP32-S3; keeps it on ESP32-P4; keeps RNDIS board logic.
main/boards/otto-robot/websocket_control_server.cc	Stubs WebSocket handler/start to avoid relying on disabled WS support.
main/boards/otto-robot/otto_robot.cc	Disables OttoRobot camera initialization (always returns false).
main/boards/otto-robot/config.h	Adds diagnostics pragmas around legacy ADC include to reduce warning noise.
main/boards/common/esp32_camera.cc	Formatting/typing tweaks and logging format fix for ESP-IDF 5.3 toolchain warnings-as-errors.
main/boards/common/esp_video.h	Comments out esp_video init include and constructor declaration.
main/assets.cc	Uses a fixed 4096 sector size instead of a newer-IDF helper API; formatting cleanups.
error.txt	Adds a captured local build log.
DEPENDENCY_CHANGES.txt	Documents dependency/version changes and rationale for the IDF 5.3.2 adaptation.
CMakeLists.txt	Adds compiler flag to avoid maybe-uninitialized being treated as error.

main/idf_component.yml:45

• esp_video dependency was removed from the component manifest, but the project still conditionally compiles boards/common/esp_video.cc for ESP32-P4 (see main/CMakeLists.txt). This will break ESP32-P4 builds because esp_video headers/components won’t be available. Either re-add espressif/esp_video under a target in [esp32p4] rule, or remove/disable the P4 esp_video sources in CMake for this branch.
