feat(ios): W4 app wiring — DI graph, event fan-out, lifecycle, privacy shade

Browse Source 
T-iOS-15: AppEnvironment production DI (real Keychain/probe/transports), EventFanOut
(engine.events → TerminalVM + GateVM + activity bridge), scenePhase lifecycle
(.background→close, suspend→rebuild+reopen reclaims size), privacy shade on != .active,
spike screen deleted, cold-start routing
Walkthrough proxies: hosted live-server smoke over the production DI graph (probe→store→
attach→echo→close) + real-Keychain kSecAttrAccessible assertion (closes T-iOS-7 deferral)
Deviation closed: TerminalViewModel.lastSentDims (valid-only) + alive-engine .active →
notifyForegrounded(dims:) (orchestrator fix on behalf of T-iOS-11 owner)
Env finding: repo under ~/Documents → TCC blocks sim-spawned node; SimServerHarness dual-mode
(self-bootstrap / WEBTERM_SERVER_URL via simctl launchctl setenv)
Verified: 214 pkg + 76 app + 10 integration tests green; verify agent 8/8 PASS

// SimServerHarness.swift — T-iOS-15 hosted live-server smoke 的基础设施。
//
// WebTermTests 跑在【模拟器内的签名 App 宿主】里：iOS SDK 没有
// Foundation.Process，但模拟器进程本质是宿主 mac 上的原生进程 ——
// `posix_spawn`（iOS 2.0+ 可用，见 SDK spawn.h）在模拟器上直接工作，
// 模拟器也能直达宿主 loopback（App 的 ATS 127.0.0.0/8 例外已在 project.yml）。
//
// 生命周期与 ios/IntegrationTests/ServerHarness.swift 同思路（death-pipe）：
// 只 spawn 一个 /bin/sh，它把真服务器（node_modules/.bin/tsx src/server.ts）
// 拉起为后台子进程后阻塞在 `read`（stdin = 本测试进程持有写端的管道）。
// 测试进程无论以何种方式退出，写端被内核关闭 → `read` 得 EOF → sh `kill` 服务器。
// 无孤儿、无需 atexit。
//
// 运行模式（同 ServerHarness 的 A/B 两式）：
// A. 自举（默认）：repo 不在 TCC 保护目录时，测试进程内 posix_spawn 起真服务器。
// B. 外部服务器：TEST_RUNNER_WEBTERM_SERVER_URL=http://127.0.0.1:<port>
// （TEST_RUNNER_ 前缀是 xcodebuild 向测试进程透传 env 的官方通道）。
// repo 根可用 TEST_RUNNER_WEBTERM_REPO_ROOT 覆盖（默认由 #filePath 推导）。
//
// TCC 硬墙（T-iOS-15 实测，2026-07-05）：repo 位于 ~/Documents|Desktop|Downloads
// 时模式 A 必挂——模拟器 App 语境 spawn 的 node 打开该目录下文件会被 tccd 无限
// 阻塞（sample 实测主线程卡 uv_cwd → __open_nocancel；sh 内 head 同样挂起；
// /bin/sh、/bin/date 等平台二进制不受影响）。此时 harness 快速失败并给出模式 B
// 的可操作指引，绝不无声挂 60 秒。CI checkout（如 /Users/runner/work）不受影响。
