Remove auto-reboot and make timezone configurable

 - Single codebase, role selected at boot via `detect_role()` (`include/config.h`, `src/config.cpp`).
 - LoRa link uses explicit CRC16 frame protection in firmware (`src/lora_transport.cpp`).
 - Sender batches up to `30` samples and retries on missing ACK (`BATCH_MAX_RETRIES=2`, retry policy `Keep`).
+- Sender meter parsing is decoupled from LoRa ACK waits using a dedicated FreeRTOS reader task + queue (`src/main.cpp`).
 - Receiver uses STA mode when config is valid, otherwise AP fallback with web config.
+- No debug auto-reboot timer is active in normal firmware loops.

 ## Sender Meter Path
 
 Implemented in `src/meter_driver.cpp` + sender loop in `src/main.cpp`:
 
 - UART: `Serial2`, RX pin `GPIO34` (`PIN_METER_RX`), `9600 7E1`
-- Frame detection: starts at `'/'`, ends at `'!'`, timeout protection included
+- ESP32 RX buffer is enlarged to `8192` bytes to survive long LoRa blocking sections.
+- Frame detection: starts at `'/'`, ends at `'!'`, timeout protection included (`METER_FRAME_TIMEOUT_MS=20000`).
+- Parsing runs in a dedicated sender task and is handed to the main sender loop via queue.
