Boots an iOS Simulator, launches Mobile Safari, exposes its Web Inspector
through ios-webkit-debug-proxy on TCP, discovers the per-tab WebSocket
URL, and runs tests/webview against it. DEBUG=pw:protocol surfaces every
wvConnection send/receive; the protocol log is tailed inline and
uploaded as an artifact.

Temporarily disables pull_request triggers on the other workflows so
this branch doesn't churn CI on every push. Markers note "restore before
merge".

iOS Mobile Safari's per-page inspector channel speaks the wrapped form
of the WebKit Inspector protocol: outgoing commands must come through
Target.sendMessageToTarget, and responses arrive in
Target.dispatchMessageFromTarget. ios-webkit-debug-proxy forwards the
WebSocket bytes transparently, so wk_wv has to do the wrapping itself.

WVConnection now exposes an outerSession that speaks the raw transport
(and handles Target.* lifecycle events) plus a lazily-created
browserSession whose _rawSend wraps every message into
Target.sendMessageToTarget. WVBrowser.connectOverCDP awaits the first
Target.targetCreated before constructing WVPage so that Page.* and
Runtime.* commands flow on the wrapping session.

iPhone 15 isn't pre-installed on the macos-15-arm64 runner; the action
errors out with "No devices found for the matching requirements" per
run 26318594713. The runner ships iPhone 16/17 series with iOS 18.x and
iOS 26.x pre-paired, so pin to iPhone 16 + iOS 18.6 for predictable
boots.

ios_webkit_debug_proxy can no longer auto-discover the iOS Simulator on
modern macOS — Apple now exposes webinspectord over a launchd-owned
Unix socket instead of a TCP port. Run 26343302032 showed the proxy
booted with an empty device list at :9221.

Locate the socket with 'lsof -aUc launchd_sim' (matching
com.apple.webinspectord_sim.socket), retry a few times in case it
appears late, and feed it to the proxy via -s "unix:<path>".
