Wraps the existing ChatInput and VoiceWaveform into the spec-canonical
input surface: voice waveform above, hairline divider, and text input
below, inside a rounded 8px near-black shell. Stateless composite —
callers pass micStream/micActive and onSend through to the underlying
primitives.

Renders a conversational home-state message as an assistant-turn bubble
when no chat is active, summarising active agents, pending gates,
recent completions, and stale projects via markdown bullets. Replaces
the old Dashboard grid for the Assistant landing route. Exposes a pure
`buildGreetingMarkdown` helper driving the unit tests.
