ChatController already transitioned through a `.connecting` state
between tap-Chat and first-message-ready (ACP initialize + session/new
take ~0.5–1.5 s on a warm network), but there was no visible UI
— the screen stayed on the idle layout with a disabled composer.
Users interpreted the silence as a frozen app (pass-1 M7 #3).

Adds a `.regularMaterial` overlay with a large ProgressView +
"Connecting to <nickname>…" text, rendered whenever
`controller.state == .connecting`. Disappears automatically when
state flips to `.ready` (normal path) or `.failed` (handoff to the
existing errorOverlay).
