Subject: [PATCH] ci: improve safety and reliability of integration logcat
 script
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR improves the stability, safety, and maintainability of the integration
test Bash script used in the Android CI pipeline.

### ✔ Summary of Improvements
This update focuses on hardening the script and preventing silent failures,
unexpected behavior, and log corruption during integration test execution.

### 🔧 Key Changes
- Enabled strict Bash mode (`set -euo pipefail`) to ensure the script stops on
  errors, avoids undefined variables, and surfaces pipeline failures.
- Quoted all variable expansions to prevent word-splitting, globbing, and
  incorrect argument parsing during CI execution.
- Replaced the hardcoded Codecov token with a secure environment variable
  (`$CODECOV_TOKEN`) to avoid credential leakage in the repository.
- Added proper cleanup logic for the background `adb logcat` process, using:
  - `wait "$LOGCAT_PID"` to flush any buffered output
  - `kill "$LOGCAT_PID" 2>/dev/null || true` to avoid CI crashes if the process exits early
- Improved the reliability of logcat upload logic and ensured that log files
  are preserved whenever an integration test step fails.
- Ensured correct exit code propagation so that Drone CI reflects accurate
  build/test results.
- General scripting cleanup and modernization to better align with Bash best
  practices and CI reproducibility.

### 💡 Why These Changes Matter
The previous version of the script:
- could continue execution after failed commands,
- could kill unrelated processes or truncate log output,
- exposed a sensitive token in plain text,
- did not properly handle asynchronous processes,
- could cause inconsistent CI behavior depending on the environment.

With these improvements, the integration test pipeline becomes:
- more secure,
- more deterministic,
- easier to debug,
- and safer for automated execution.

### 🧪 Testing Notes
Only CI-related behavior was modified.
No app logic was touched.
This PR has been tested across multiple invocations to confirm stable behavior
and proper log handling.

This PR does not affect end users but significantly improves CI reliability for
maintainers and contributors.
