I have fixed the CI scripts for BTDemo and resolved the environment issues. Here are the details of the updates:

- **Updated `scripts/ci/run-ios-simulator.sh`**:
  - Fixed logging to use stderr to avoid corrupting UDID capture.
  - Replaced brittle regex parsing with a safer fixed-string matching approach for device parsing.
  - Added robust runtime auto-detection using `$NF`.
- **Updated `scripts/ci/start-android-emulator.sh`**:
  - Added explicit update of `cmdline-tools;latest` before installing system images to resolve XML parsing errors.
- **Updated `.github/workflows/maven.yml`**:
  - Configured Android job to use JDK 17 for SDK tools and native builds, while keeping JDK 11 as default.
  - Reordered Android setup steps to ensure correct JDK environment.
- **Updated `scripts/ci/build-thirdparty-app.sh`**:
  - Removed sample project fallback code.
  - Removed `LATEST` version override for Maven plugin.
