roboscript update (fixes #7986)

[jessewashburn]

This PR introduces a Robo test workflow for myPlanet. The goal is to automatically exercise a “happy path,” surface crashes, and capture video + logs of the session.

Setup

Install gcloud if you don't already have it.

You will need a json key to use it, which I've shared privately. Save it locally and run:

gcloud auth activate-service-account --key-file <path-to-key>
gcloud config set project myplanet-ci

How to run locally

1. Build an APK:

   ./gradlew assembleDebug

   Output: app/build/outputs/apk/default/debug/app-default-debug.apk

2. Run the Robo test:

   ./ci/robo/run_robo.sh

This script:

• Uploads the APK and ci/robo/myplanet_robo.json to Firebase Test Lab
• Runs a scripted crawl (login as robouser → explore → logout → guest)
• Stores results in our shared GCS bucket myplanet-test-results
• Prints public result links (video, logcat, actions.json, etc.) that can be opened directly in the browser

---

Example output

When you run ./ci/robo/run_robo.sh, you’ll see console output like this:

Raw results will be stored in your GCS bucket at:
  https://console.developers.google.com/storage/browser/myplanet-test-results/local-test/20251003_151542/

Test results will be streamed to:
  https://console.firebase.google.com/project/myplanet-ci/testlab/histories/bh.ee944f68bb5b60d1/matrices/8182797315128267371

At the end it also prints handy public links, e.g.:

Public result links (if bucket is public):
  Folder:  https://storage.googleapis.com/myplanet-test-results/local-test/20251003_143830/
  Video:   https://storage.googleapis.com/myplanet-test-results/local-test/20251003_143830/Pixel2.arm-29-en-portrait/video.mp4
  Logcat:  https://storage.googleapis.com/myplanet-test-results/local-test/20251003_143830/Pixel2.arm-29-en-portrait/logcat
  Actions: https://storage.googleapis.com/myplanet-test-results/local-test/20251003_143830/Pixel2.arm-29-en-portrait/actions.json
  APK:     https://storage.googleapis.com/myplanet-test-results/local-test/20251003_143830/app-default-debug.apk

---

Each run contains:

• video.mp4 – full test session
• logcat – Android logs
• actions.json – steps executed
• screenshots – sequence of screens
• app-default-debug.apk – tested APK

Since the bucket is public, you can open results directly in the browser using the printed links.

Next steps

• Expand the happy path (deeper navigation, language toggles, etc.)
• Automate via GitHub Actions so runs happen on every new build
