Add board support for the Seeed XIAO ESP32S3 Sense (ESP32-S3R8, 8MB flash / 8MB PSRAM): OV2640/OV3660 DVP camera, PDM digital microphone, onboard LED (GPIO21), BOOT button (GPIO0), and optional microSD. - New board dir boards/ESP32/SEEED_ESP32S3_XIAO_SENSE with camera / PDM mic / LED|button / SD registration; LED and SD share GPIO21, so ENABLE_LED is Kconfig-gated on !ENABLE_SEEED_XIAO_SDCARD. - New common PDM mic TDD driver (tdd_audio_pdm_mic): mic-only capture via ESP-IDF I2S PDM RX, guarded by SOC_I2S_SUPPORTS_PDM_RX so non-PDM targets still build. - Register the board in boards/ESP32/Kconfig.

Add a way for a camera driver to advertise which output formats it supports, so applications can query capabilities instead of trying an open() and handling the error. Previously the TDD dev_info only carried a single native raw format (sr_fmt), which was write-only in TDL. - Replace the single fmt/sr_fmt field with a supported_fmts bitmask (TDL_CAMERA_FMT_E) in TDD_CAMERA_DEV_INFO_T and TDL_CAMERA_DEV_INFO_T; surfaced via tdl_camera_dev_get_info(). 0 = unspecified (probe via open, preserving old behavior for drivers that don't set it). - Fill it per driver from what open() accepts: ESP DVP (OV2640) and ESP CSI (P4) = YUV422|JPEG; core DVP (T5AI) = YUV422|JPEG|H264; Linux v4l2 = YUV422|JPEG. Only ESP32-S3 was build-verified; T5AI and Linux changes are field renames with correct masks but were not compiled here. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- output_sdcard: pick the camera output format at runtime from the driver's supported_fmts (prefer H264, else JPEG) instead of hardcoding H264, so it runs on ESP32-S3 (JPEG) as well as T5AI (H264). File extension follows the chosen format. - output_web: new example streaming the camera to a web browser as MJPEG over HTTP (WiFi STA + tiny HTTP server); frames buffered in PSRAM, Nagle disabled for smoother streaming. For camera boards without a display. Configs for SEEED_ESP32S3_XIAO_SENSE and TUYA_T5AI_BOARD. - Add SEEED_ESP32S3_XIAO_SENSE board configs to led, switch_demo and camera_demo.

Reorganize the audio examples so audio_codecs is a container with two leaves that name their output path: - output_speaker: the former audio_codecs (record then play back through a speaker/codec). - output_sdcard: the former multimedia/audio_recorder/output_sdcard (record the mic to a WAV file on SD). Moved here and removed the now empty multimedia/audio_recorder. Also: rename the recorder output to record.pcm/record.wav — ESP-IDF FATFS defaults to 8.3 short names, so "tuya_recorder.wav" failed to open; and add a SEEED_ESP32S3_XIAO_SENSE config for output_sdcard.

camera_demo has a pre-existing build break (tuya_p2p headers use undefined CHAR_T/UINT_T), so it does not compile for any board. Remove the SEEED_ESP32S3_XIAO_SENSE config so CI does not try (and fail) to build camera_demo for this board. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
