Wired control path so the S3 hub can set delay/volume on the source boards and read their status, over an I2C bus (separate from the audio I2S bus). - src/hub_proto.h: shared protocol — addresses (JBL 0x10, Cardo 0x11), commands SET_DELAY (u16), SET_VOLUME (u8), GET_STATUS (4-byte payload: connected, delay LE, volume). - board_source.cpp (B/C): I2C slave on GPIO32/33 (addr via -DHUB_I2C_ADDR). Light onReceive/onRequest callbacks stash requests; loop() applies them (reuses set_delay; adds current_volume -> source.set_volume, NVS-persisted). Relay/FIFO/touch untouched. - hub_s3.cpp: I2C master on Wire1 (GPIO15/16) — peripheral 1, since the CST816S touch owns peripheral 0. Polls both boards ~1Hz; LovyanGFX UI shows each speaker's connect/delay/volume with touch +/- zones that send commands. - platformio.ini: -DHUB_I2C_ADDR per source env. Written by two parallel sub-agents (one per side) against hub_proto.h; fixed the Wire->Wire1 peripheral conflict. All three envs build clean.
