Polish WASD and Q/E camera navigation

[NellInc]

Summary

• unify WASD, arrow, Q/E, and Shift input across orbit and desktop first-person camera paths using physical key codes
• stop camera motion while interface controls have focus, on blur, on hidden tabs, and after camera-mode unmounts
• keep the orbit target aligned with collision-accepted camera travel so walls and world bounds do not twist the view
• add collision-aware Q/E altitude control to the optional Rapier first-person path
• pause auto-rotation during manual movement, cap suspended-tab delta spikes, and document the complete controls
• retain MillOS v0.40, the unified authored world, and the strict uncrewed contract

Validation

• npm run typecheck
• npm run lint
• npm run format:check
• npm test -- --reporter=dot (96 files, 999 tests)
• VERSION=v0.40 npm run build (3,589 modules)
• npx impeccable detect src
• npm audit --audit-level=high (0 vulnerabilities)
• asset, depth, shader, bundle, uncrewed, and release-matrix validators
• focused camera navigation and collision tests (12 assertions across 2 files)
• headed browser telemetry for W, S, A, D, E, Q, Shift acceleration, and focus safety
• headed visual inspection of the reset overview after navigation
