ed1542ae11 feat: rewrite UWB firmware for DW1000 (all 3 boards) 
Anchor (esp32/uwb_anchor):
- DW1000Ranging library (200m range, MODE_LONGDATA_RANGE_ACCURACY)
- Unique addresses per anchor (anchor0/anchor1 build envs)
- +RANGE output: anchor_id, tag_addr, range_mm, rssi
- ESP-NOW receiver: forwards tag packets + priority E-STOP to Jetson
- AT+ID? command

Tag with Display (esp32/uwb_tag):
- DW1000Ranging as tag, auto-discovers anchors
- SSD1306 OLED: big distance, per-anchor ranges, RSSI bars, link status
- ESP-NOW broadcast: range/heartbeat/estop packets
- E-Stop on GPIO 0 (BOOT button), 10Hz TX while held
- Display at 5Hz, ranging driven by DW1000Ranging.loop()

Shared:
- lib/DW1000/ extracted from mf_DW1000.zip (Makerfabs fork)
- lib_extra_dirs for PlatformIO to find local library

a4879b6b3f feat: ESP32 UWB Pro anchor firmware — DS-TWR responder (Issue #544) 
Anchor firmware for Makerfabs ESP32 UWB Pro (DW3000 chip). Two anchors
mount on SaltyBot (port/starboard), USB-connected to Jetson Orin.

- DS-TWR responder: Poll→Resp→Final with ±10cm accuracy
- Streams +RANGE:<id>,<mm>,<rssi_dbm> on Serial 115200
- AT command interface: AT+RANGE?, AT+RANGE_ADDR=, AT+ID?
- ANCHOR_ID 0/1 set at build time (env:anchor0 / env:anchor1)
- PlatformIO config for Makerfabs MaUWB_DW3000 library
- udev rules for /dev/uwb-anchor0 /dev/uwb-anchor1 USB symlinks
- Pin map: SCK=18 MISO=19 MOSI=23 CS=21 RST=27 IRQ=34
