- Line 40: Ensure the runner at RUNNER_APP is fresh before the XCTest.framework
directory check, removing the previous exported runner before copying the new
one so stale frameworks cannot cause the check to skip the required copy.

Problem
Runners built locally with Xcode 27.1 don't start on simulators:
make sim-install: the runner fails at launch withdyld: Library not loaded: @rpath/XCTest.framework/XCTest. Xcode 27 no longer embeds XCTest, XCTestCore, XCUIAutomation, etc. intodevicekit-iosUITests-Runner.app/Frameworks(the folder is empty in build products).make sim-zip-*:zip -rupdates an existing zip instead of replacing it, so a fresh build was merged into an old zip from an earlier Xcode. That left an oldTesting.frameworknext to the new_Testing_Foundation.frameworkcopied bypatch-runner.sh, and the test bundle failed to load withSymbol not found: _$s7Testing12FileClonableMp. The agent never answers, and mobilecli times out with "timed out waiting for WebDriverAgent to be ready".Fix
scripts/patch-runner.sh: if the runner has noXCTest.framework, copy the XCTest frameworks andlibXCTestSwiftSupport.dylibfrom the selected Xcode's platform directory. Runners that Xcode already filled in (Xcode 26) are left alone.Makefile:rm -feach zip/ipa beforezip -r.Test plan
make sim-zip-arm64: the zip contains a matching set of test frameworksipa-unsignedwith Xcode 27 on a real device
