{
  "progress": {
    "percent": 96.29631

To reproduce

Open a terminal:

./arduino-cli daemon
Daemon is now listening on 127.0.0.1:50051
{"IP":"127.0.0.1","Port":"50051"}

In another terminal:

tree my_sketch             
my_sketch
└── my_sketch.ino

1 directory, 1 file

cat my_sketch/my_sketch.ino
void setup() {}
void loop() {}

Expected behavior

Clients receive completed: true once. When completed: true, then percent is 100.
