fix(cli): skip redundant settings uploads when unchanged

Only upload settings when edited values differ from current device settings to avoid unnecessary resets.

 # led-tool
-- `-s, --show`: Display current settings from device
-- `--no-download`: Don't download settings first (use empty settings)
-**Default behavior:** Downloads settings and prints them. If any edit flags are provided, settings are modified and uploaded automatically (unless `--no-upload` is specified).
 
-## Device Connection
+CLI helpers for MicroPython LED devices: **`settings.json`** download/upload via **mpremote**, resets, follow/tail, recursive uploads, optional firmware flash, and **led-driver**-oriented flags (presets, transport, Wi-Fi fields).
 
-The tools use an integrated mpremote transport to communicate with MicroPython devices. Make sure your device is connected and accessible via the specified serial port.## LicenseSee LICENSE file for details.
+Connection is always via **`-p` / `--port`** (default `/dev/ttyACM0`). There is **no** separate “server IP” flag; the Pi or PC address is configured on the device in **`settings.json`** when using Wi-Fi mode.
+
+## Common flags
+
+| Flag | Purpose |
+|------|--------|
+| `-p`, `--port` | Serial device (default `/dev/ttyACM0`) |
+| `-s`, `--show` | Print current settings from the device |
+| `-n`, `--name` | Device **name** |
+| `--reset-device-name` | Set **name** to firmware default (`led-` + STA MAC hex, same as `Settings.set_defaults` on led-driver) |
+| `--id` | Numeric device id (ESP-NOW, 0–255) |
+| `--pin` | LED GPIO (`led_pin`) |
+| `-b`, `--brightness` | Brightness 0–255 |
+| `-l`, `--leds` | LED count (`num_leds`) |
+| `-d`, `--debug` | Debug 0 or 1 |
+| `-o`, `--order` | LED colour order (`rgb`, `grb`, …) |
+| `--preset` / `--pattern` | Create or replace a named preset in **led-driver** `presets.json` |
+| `--default` | Startup preset name |
+| `--transport` | `espnow` or `wifi` (`transport_type` on device) |
+| `--ssid`, `--wifi-password`, `--wifi-channel` | Wi-Fi / channel fields for the driver |
+| `-r`, `--reset` | Reset the device |
+| `-f`, `--follow` | Follow serial output (optional timeout seconds) |
+| `--pause` | Sleep N seconds (for chained actions) |
+| `-u`, `--upload` | Recursive upload: `-u SRC [DEST]` |
+| `--src`, `--lib` | Upload `src/` or a tree to `/lib` |
+| `-e` | Erase device code (keeps `settings.json`) |
+| `--rm` | Remove a path on the device |
+| `--flash` | Flash a firmware binary (uses **esptool** on the host) |
+
+**Default behaviour:** the tool always downloads `settings.json`, prints the merged view, and uploads again **only** when you pass setting edits (`--name`, `--leds`, …), **`--preset`**, or the relevant upload/flash/erase actions in order.
+
+Run **`python cli.py -h`** for the full epilog and argument list.
