Subject: [PATCH] feat(js): add BLE GATT client to the ble module

Adds a minimal GATT client to the bjs `ble` module so scripts can connect
to a BLE peripheral and read/write its characteristics (NimBLE 2.x):

  ble.connect(nameOrAddress, timeoutSec?) -> bool
  ble.isConnected() -> bool
  ble.read(serviceUUID, charUUID) -> Uint8Array | null
  ble.write(serviceUUID, charUUID, Uint8Array|string, withResponse?) -> bool
  ble.disconnect()

connect() scans for up to timeoutSec seconds and connects to the first device
whose name starts with the given string (case-insensitive) or whose MAC
matches. On NimBLE 1.x builds the new functions throw "not supported".

Includes sd_files/interpreter/crafty.js, an example remote for the
Storz & Bickel CRAFTY/CRAFTY+ (target/boost temperature, heater on/off,
battery), and the regenerated mqjs headers.
