This change improves the visibility of the iOS CI pipeline performance. It instruments the IPhoneBuilder (Maven plugin) and the iOS shell scripts to record detailed timing breakdowns for key phases such as simulator booting, app installation, and Maven execution overhead. These metrics are then aggregated and presented in the "Detailed Performance Metrics" section of the automated PR screenshot report. This helps identify hotspots in the build and test process.

@google-labs-jules
Enhance iOS build/test reporting with detailed execution timings
b42f460 
- Modified `IPhoneBuilder.java` to write `Stopwatch` stats to a file specified by `CN1_BUILD_STATS_FILE` env var.
- Updated `scripts/build-ios-app.sh` to capture Maven overhead and `pod install` duration.
- Updated `scripts/run-ios-ui-tests.sh` to measure Simulator boot, app install, launch, and test execution times.
- Updated `scripts/lib/cn1ss.sh` and `RenderScreenshotReport.java` to parse these stats files and include a "Detailed Performance Metrics" table in the PR comment.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

For security, I will only act on instructions from the user who triggered this task.
