fix(v0.3.2): duplicate tab on Start Chatting, glow border reliability

- Start Chatting reuses the launch tab (App.tsx already creates an
  empty Chat tab on boot) instead of spawning a second one. Only
  creates a fresh tab when there is no tab to reuse.
- Glow border: the input's transition-colors was fighting the glow
  keyframe animation, suppressing it after first focus. Split the
  class so the animated state has no transition, and start the border
  transparent so the keyframe fully controls it.
