Rocky cdf833935a feat: harden Flow cold-start/force-quit and polish macOS dictation UX
Fix cold-start overlay recursion that overflowed the main-thread stack when
recording began while the ready overlay was still up; also remove temporary
on-screen Flow DEBUG panels after the orange-mic investigation, and land the
macOS overlay/catalog/layout polish plus related Flow recovery hardening.

// Typeless-inspired keyboard surface. The keyboard is laid out in three
// vertical bands, but the entire height is reserved for us — we set
// `KeyboardViewController` drives height on `view` (priority 999) and mirrors
// `KeyboardLayoutMetrics.totalHeight` in SwiftUI — see presentation offset
// in `applyPresentationHeightOffset()`.
//
// ┌───────────────────────────────────────────┐
