Adds runtime speaker-sync control to the relay: - src/relay_config.h: shared Wi-Fi AP creds + ESP-NOW RelayDelayMsg (delay_ms[JBL], delay_ms[Cardo]) on a fixed channel. - board_sink.cpp (Board A): hosts a Wi-Fi AP "BikeAudio-Setup" + a small web UI (two sliders, no app) at 192.168.4.1, and broadcasts the chosen per-speaker delays to the source boards over ESP-NOW. Still A2DP sink + I2S master. (Tune while parked — Wi-Fi/BT coexist on one radio.) - board_source.cpp (Boards B/C): inserts an adjustable delay line between I2S in and A2DP out — a dedicated reader task fills a ring buffer (up to ~250 ms) and the A2DP callback reads delay_frames behind the write head. Delay arrives via ESP-NOW (per SPEAKER_ID) and is persisted to flash (Preferences), so it survives power cycles. - platformio.ini: source envs get -DSPEAKER_ID (0=JBL, 1=Cardo). Lets the rider trim JBL vs Cardo timing to sync the two speakers. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

; reach only one speaker — so the work is split across three boards that share

; an I2S bus. See README.md for wiring and the flash order.
