[codex] Improve localized iOS Simulator panel controls

[niyyzf-lab]

Summary

• support localized Chinese Codex right-panel/menu labels and side-panel controls
• keep helper binaries out of the watched tweak directory to avoid self-reload during first use
• target input forwarding to the captured simulator UDID and recover from stale HID mach ports after simulator restarts
• add an explicit desktop/Home toolbar button
• forward keyboard text and navigation keys from the Codex panel into the simulator

Validation

• /Applications/Codex.app/Contents/Resources/node --check index.js
• /usr/bin/clang -fobjc-arc -O2 -framework Foundation -framework CoreGraphics helpers/sim-input.m -o /tmp/codexpp-sim-input-check
• /usr/bin/swiftc -O -framework ScreenCaptureKit -framework CoreImage -framework AppKit -framework CoreMedia -framework CoreVideo helpers/sim-capture.swift -o /tmp/codexpp-sim-capture-check
• manually verified Chinese UI injection, simulator touch interaction, Expo app interaction recovery, Home button, and keyboard text forwarding
