perf(app): defer inactive shell tools

[Itsnotaka]

Summary

• defer the disabled New York sidebar view while keeping extension state and exact pane geometry eager
• defer the closed Connect Device controller behind a lightweight request/resume store
• preserve exact sidebar and Connect Device skeleton geometry and add startup graph guards

Performance

• eager app source: 1,256.5 KiB -> 1,208.0 KiB (-3.86%)
• median Electron window-created-to-ready: 5,094 ms -> 4,987 ms (-2.10%)
• median first post-ready frame: 5,105.6 ms -> 4,998.4 ms (-2.10%)
• median initial React render: 2.0 ms -> 1.9 ms
• median commit-to-next-frame: 6.4 ms -> 5.6 ms

Temporary profiler probes were removed after the bounded dev-time review.

Verification

• 57 focused extension and Connect Device tests pass
• app production build passes
• startup graph guard passes
• targeted Oxlint and formatting pass
• app typecheck: inherited onboarding-layout.tsx gearColossus error only
• repo architecture/design: inherited oversized-file and v2.tsx violations only
