First classic-ESP32 (non-S3) board in the firmware, and first SX127x radio. ESP32 + SX1276 + SSD1306 OLED + AXP192 PMIC, CP2102 USB-UART bridge. Pin map verified from MeshCore variants/lilygo_tbeam_SX1276. The AXP192 gates power to the LoRa chip and OLED. Its I²C bus is shared with the display, so the firmware builds I²C0 in blocking mode first for the PMIC init, then converts the same handle to async and hands it to the display task — avoids double-consuming the peripheral. Lora-phy's Sx127x support drives DIO0 as the sole IRQ (SX127x has no BUSY line); the chip runs from a crystal, tx_boost routes +20 dBm through PA_BOOST. The `esp-hal` / `esp-rtos` / `esp-backtrace` / `esp-println` deps have been restructured so the chip flavour (esp32 vs esp32s3) is selected at the per-board feature level instead of baked into the dep lines. This keeps the existing S3 boards building on esp32s3 while the new T-Beam feature selects classic esp32 via the same dependency set. LoRaBoard gains supported_sf_bitmap() / supported_bw_bitmap() methods (with SX126x defaults) so the T-Beam can report SF6–SF12 via GET_INFO — the SX1276 has no SF5. radio_chip_id() reports 0x0011 per donglora-protocol RadioChipId::Sx1276. freq_range_hz widens to the SX1276 datasheet span of 137 MHz–1020 MHz. New modules: - src/hal/esp32.rs — classic-ESP32 MCU primitives - src/board/esp32.rs — Sx127x radio + SSD1306 display pipe - src/board/lilygo_tbeam.rs — the board file - src/driver/axp.rs — AXP192 init added alongside AXP2101
