Port paired wireless inspection client

[nova286]

Summary

• ports the macOS half of Feature: 无线连接 hughkli/Lookin#42 while preserving original author commits
• pairs with Port and harden opt-in wireless inspection LookinServer#3 and pins the exact reviewed server commit
• preserves this fork's SwiftUI Inspector toolbar mode
• generalizes request, push, and cancellation paths across Peertalk and wireless channels
• adds launch/workspace wireless device selection, first-use authorization flow, auto-connect preference, 30-second authorization timeout, main-thread UI state handling, localized UI, and privacy-safe logging
• documents trusted-LAN usage and the plaintext/non-cryptographic security boundary

Deliberately excluded

• personal bundle ID/signing changes
• upstream merge commits
• dependencies pointing at contributor forks

Validation

• pod install with CocoaPods 1.17.0
• property lists and localization strings: passed plutil -lint
• universal macOS Release build (arm64 x86_64, code signing disabled): passed
• git diff --check and git diff --cached --check: passed

Remaining manual gate

A physical iPhone and Mac on the same LAN are still required to verify Bonjour discovery, the iOS authorization prompt, hierarchy loading, attribute editing, reconnect, and explicit shutdown. Keep this PR in draft until both repositories pass CI and that device check is complete.
