- DTS: migrate i2c0 from legacy esp32-i2c to esp32-i2c-master to avoid IDF CONFLICT warning (driver_ng vs old driver) which could stall boot - Configuration.cpp: add 100ms power stabilize after GPIO46 amp on, probe ES8311 at 0x18 with has_device_at_address before full init (non-fatal), prevents bus lock if codec missing - ST7305Display.cpp: add 150ms after reset + 50ms after init, prevents freeze on fast boot where SPI transaction too early (observed stuck on weird state) Build 0x2b79c0 -> 0x2b79c0 with I2C master, ES8311 now initializes, display stable Co-Authored-By: internal-model
