Pull WLED state from device; add Sunrise preset and presets docs

- wled_pull: update full.json, state.json, info.json from device
- Add wled_config/presets/sunrise.json (psave payload for preset 1)
- README: document defining and pushing presets

+### Brightness and white channel
+
+WLED has three separate level-style controls:
+
+| Control | JSON | Description |
+|--------|------|--------------|
+| **Global brightness** | `state.bri` | Main dimmer for the whole light (0–255). When off, this is the brightness used when you turn on. |
+| **Segment brightness** | `state.seg[].bri` | Per-segment brightness (0–255). Multiplies with the segment’s color/effect. |
+| **White channel** | `state.seg[].col[0][3]` | The W in RGBW: primary color is `[R, G, B, W]`. White channel 0–255 (how much dedicated white is mixed in). |
+
+**CLI:**
+
+- `--bri N` — global brightness.
+- `--seg-bri N` — segment 0 brightness.
+- `--white N` — segment 0 primary color’s white channel (0–255). Use with Solid effect for predictable results.
+
+```bash
+python wled_push.py --on --bri 200           # global only
+python wled_push.py --seg-bri 128            # dim segment 0 only
+python wled_push.py --white 255              # full white channel (segment 0)

+Your WLED device (**WLED-Gledopto** at `192.168.240.30`) supports **CCT** (color temperature). This controls the **warm vs cool** blend of the white output; the **white channel** (`--white`) controls how much white is mixed in (e.g. with RGB). In the API, segment `cct` uses a relative scale:
 
 - **`cct: 0`** → warmest (warm white, ~2700 K)
 - **`cct: 255`** → coolest (cool white, ~6500 K)

 `wled_config/` holds JSON pulled from the device: `full.json`, `state.json`, `info.json`. Use `wled_push.py --file wled_config/state.json` to restore state.
 
+### Presets (define in JSON, push to device)
+
+Presets are stored on the WLED device; you can **define** them in JSON and **push** once to create/update them. Use the WLED `psave` API: include `psave` (preset slot 1–250), optional `n` (name), `ib` (include brightness), and the state you want saved.
+
+**Example — Sunrise preset** (warm white, Solid, for the 8am alarm):
+
+```bash
+python wled_push.py --file wled_config/presets/sunrise.json
+```
+
+That sends the payload in `wled_config/presets/sunrise.json` to the device. The device saves it as preset ID 1 named "Sunrise". Home Assistant can then use `select.wled_gledopto_preset` with option "Sunrise" in the sunrise alarm script.
+
+- **full.json** is a snapshot from **pull** (state + info + effects + palettes). It does not define presets; use `wled_config/presets/*.json` for that.
+- To add more presets: create a new JSON file with `psave`, `n`, and state, then run `wled_push.py --file path/to/preset.json`.
+
 ## Sunrise alarm
 
 `wled_config/sunrise_8am.json` starts a 30-minute sunrise that finishes at `08:00`.
