Docs: document zone-based scanning; make version example non-drifting

The Scanning section only said 'per upstream OpenGD77', which left the
scan-list question unanswered. Explain that zones are the scan list, the
Zone Skip / All Skip flags, the start key and the Radio options settings.
Also replace the version example that goes stale every release.

 ### Scanning — ⚪ [OpenGD77]
-Channel and VFO scanning with hold/pause behaviour, per the upstream OpenGD77
-controls.
+**There are no scan lists.** Unlike the vendor CPS, OpenGD77 scans **the channels
+of the currently selected zone** — so a zone *is* the scan list. To scan a
+particular set of channels, put them in a zone and select it. The **All Channels**
+virtual zone scans every channel in the codeplug.
+
+- **Start/stop:** long-press **UP** on the Channel or VFO screen (**RED** stops).
+- **Exclude a channel:** **Menu → Channel details** (or **SK2 + green** on the
+  Channel screen) → **Zone Skip** (skipped when scanning a normal zone) and
+  **All Skip** (skipped when scanning *All Channels*).
+- **Settings:** **Menu → Options → Radio options** → **Scan delay**,
+  **Scan dwell**, **Scan mode** (Hold / Pause / Stop) and **Scan On Boot**.
+
+Note: in the codeplug these two skip flags reuse the old "Auto Scan" and "Lone
+Worker" bits, so a vendor CPS may label them differently — set them on the radio
+to avoid confusion.
