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.

+  contacts (or type a DMR ID manually and press **DOWN** to move to the text).
+- **Contacts list shows everything** — Menu → Contacts now lists all contact
+  types together under the title "Contacts" instead of defaulting to the group
+  filter; **HASH** still cycles the per-type filters (all / groups / private /
+  all-call).
+
+## 0.9.0
+
+- **Pride theme** — the status/header bar and the menu title bar are now painted
+  in the top rainbow-stripe colour so they blend into the background instead of
+  showing as white boxes.
+
+## 0.8.0
+
+- **Three new theme presets** (Display Options → "Theme"): **Red** (black-on-red
+  day / red-on-black night); **Neon 80s**, an 80s-synthwave palette that maps
+  several neon colours (cyan, magenta, violet, green, yellow) across the
+  individual UI elements over a dark background; and **Pride**, which paints the
+  background as a rainbow pride flag with black text and white menu/header boxes
+  kept readable over the stripes.
+- **Build:** each build now prints a per-region memory-usage summary
+  (FLASH / RAM / CCMRAM used, size and free) so the remaining headroom is

   inactivity (Auto backlight mode); new setting in Display Options.
+- **DMR text messages (SMS)** — send and receive text messages on the radio,
+  compatible with BrandMeister, hotspots and OEM radios. Compose on the keypad
+  (or pick the recipient from your contacts), inbox/sent boxes, quick-text
+  templates, delivery confirmation and an incoming-message popup (see the manual
+  for details).
 - **Theme presets** — pick a colour theme on the radio: **Custom** (CPS-editable,
-  default), **BASIC 80s** (Commodore 64), **Terminal** (green-on-black), or
-  **Vertexic** (amber/orange). CPS edits only affect Custom.

+  **Vertexic** (amber/orange), **Red**, **Neon 80s** (multi-colour synthwave),

 - **On-radio channel management** — create and delete channels directly from the
   Channel quick menu, no PC/CPS required (see [Managing channels](#managing-channels-on-the-radio)).
+- **CRT-style shut-off animation** — the current screen collapses to a line and
+  then a dot, like an old CRT switching off (replaces the "Power Off" message).
 - **DMR reliability fix** — resolves a hard-fault (freeze needing a battery pull)
   on the DMR path that affected recent self-built OpenGD77 revisions.

 codec is merged in at flash time — see below). The build is always clean (`rm -rf build`),
 so building one platform overwrites the other's output.
 
+Each build finishes with a **memory-usage summary** — used, size and free bytes for the
+FLASH (code), RAM and CCMRAM regions — so the remaining headroom for new features is
