perf(app): defer closed shell overlays

[Itsnotaka]

What changed

• keep shell stores, controllers, hotkeys, and triggers eager while loading Command Menu, Connect Device, Settings, and toast visuals only when requested
• preserve the permanent popup/card geometry with token-driven loading frames during the first local chunk handoff
• extend the development startup gate so these four closed visual modules cannot return to the eager graph

Why

These shell-owned components rendered no visible UI during a normal Electron launch, but their full visual trees, icons, QR code path, settings rail, and toast cards were still parsed and compiled at startup.

The first open now pays one local chunk import; subsequent opens use the renderer module cache. State, dismissal, pairing resume, route mounting, and toast timers stay eager.

Performance

• eager app source: 1,527.9 KiB → 1,470.7 KiB (-3.74%)
• Electron window creation → ready-to-show median: 6,932 ms → 6,735 ms (-2.84%, three development starts)
• production initial JS: 3,041,442 B → 2,980,917 B raw (-1.99%); 915,074 B → 901,658 B gzip (-1.47%)
• process-wide Electron median: 7,849 ms → 7,792 ms (-0.73%); sidecar startup dominates this clock

No release benchmark loop or UI automation was used.

Validation

• pnpm --filter @honk/app dev:startup-review (0/4 closed visuals eager; Vite started)
• pnpm --filter @honk/app build
• 46 focused connect-device/settings tests
• React Doctor: 92/100, with the existing command-menu manual-memoization warning only
• focused Oxfmt and Oxlint

Repository-wide checks retain main's existing failures: onboarding-layout.tsx references missing gearColossus, five files exceed the architecture limit, and v2.tsx has design-lint findings. This PR adds no findings to those checks.
