feat v1.27.0: RGB light colors + red alarm pulse (issue #3)

- lightColorOf(): on+rgb_color tints icon/glow/ripple (explicit ripple color wins);
  brightness ignored by design; off/white/unavailable unchanged
- isAlarmState(): leak/smoke/gas/CO/safety/tamper/problem sensors and sirens in
  'on' pulse a red ring over any display mode; outages never alarm;
  prefers-reduced-motion honoured
- +2 unit tests, smoke_rgb_alarm.mjs, TESTING.md rows

 # Changelog
 
+## v1.27.0 — 2026-07-21 (RGB light colors + alarm pulse; issue #3)
+- **RGB lights show their actual color**: an "on" light with a color tints its
+  bulb icon, glow and — unless a custom ripple color is set — its presence ripple.
+  Brightness is deliberately ignored (a dim red bulb still reads red); off,
+  white-only and unavailable lights look as before. (Pure `lightColorOf`.)
+- **Emergencies pulse red**: leak / smoke / gas / CO / safety / tamper / problem
+  binary sensors and sirens in `on` get a red pulsing ring over any display mode.
+  `unavailable`/`unknown` never alarm — an outage is not a fire. Honours
+  `prefers-reduced-motion`. (Pure `isAlarmState`.)
+
 ## v1.26.0 — 2026-07-21 (state-reflecting icons + value display; issue #3)
 - **Auto icons now reflect live state**, like core HA: door/window/garage sensors
   swap open↔closed variants, locks show locked/unlocked, a bulb lights up as

Lesson: #8995 was auto-closed by hacs-bot — the PR body MUST be their exact template with every checkbox ticked and all 3 links (release, HACS action run, hassfest run); a custom body gets closed without discussion |
