Add cloud/CI environment detection utility

[Copilot]

Provides programmatic detection of whether code is running in CI/cloud environments (GitHub Actions, Azure Pipelines) vs local development.

Implementation

• EnvironmentDetector - Static utility class checking Platform.environment for CI indicators (CI, GITHUB_ACTIONS, TF_BUILD)
• Shell script - Bash-based detector for environments without Flutter/Dart
• CLI tool - Dart executable for standalone environment reporting
• Test suite - Validates detection logic across platforms

Usage

import 'package:dart_wing_mobile/utils/environment_detector.dart';

// Detect cloud execution
if (EnvironmentDetector.isRunningInCloud) {
  Logger.level = LogLevel.debug;  // Verbose logging in CI
  testTimeout = Duration(minutes: 5);  // Longer timeouts
}

// Get platform details
print(EnvironmentDetector.ciPlatform);  // "GitHub Actions" | "Azure Pipelines" | "Local"

Or via shell:

./scripts/check_cloud_environment.sh

Current Environment

This PR was created in GitHub Actions (github-hosted runners), validated by the implementation itself.
