Add xcodebuild output formatter with config file support

[phuongddx]

Summary

Adds real-time xcodebuild output streaming with automatic formatter detection (xcbeautify/xcpretty) and configuration file support for verbose mode.

Changes

1. Xcodebuild Output Formatter

• New: lib/xcframework_cli/xcodebuild/formatter.rb
  • Auto-detects xcbeautify or xcpretty availability
  • Streams xcodebuild output in real-time when verbose mode enabled
  • Pipes output through formatters for colored, formatted display
  • Falls back to plain streaming if no formatter available

2. Wrapper Integration

• Updated: lib/xcframework_cli/xcodebuild/wrapper.rb
  • Integrate formatter into execute method
  • Add use_formatter parameter to archive and create-xcframework commands
  • Stream output when verbose mode is enabled
  • Maintain backward compatibility

3. Configuration Support

• Updated: lib/xcframework_cli/config/defaults.rb
  • Add verbose: false and use_formatter: true defaults
• Updated: lib/xcframework_cli/config/schema.rb
  • Validate new build options in config files

4. Build Pipeline Integration

• Updated: lib/xcframework_cli/cli/commands/build.rb
  • Read verbose setting from config file
  • CLI options override config file settings
  • Apply verbose mode to logger before build starts
• Updated: lib/xcframework_cli/builder/orchestrator.rb
  • Pass use_formatter option to archiver
• Updated: lib/xcframework_cli/builder/archiver.rb
  • Forward formatter options to xcodebuild wrapper

5. Documentation

• Updated: config/examples/basic.yml
  • Document verbose and use_formatter options
• Updated: Example/SwiftyBeaver/.xcframework.yml
  • Enable verbose mode in example

Usage

Via Config File (New!)

```yaml
build:
verbose: true # Enable verbose output
use_formatter: true # Use xcbeautify/xcpretty
```

```bash
./bin/xcframework-cli build --config .xcframework.yml
```

Via CLI Flag (Existing)

```bash
./bin/xcframework-cli build --project MySDK.xcodeproj --verbose
```

What You See

✅ Real-time build logs:

• `[MySDK] Linking MySDK`
• `[MySDK] Generating MySDK.framework.dSYM`
• Compilation progress, warnings, errors

✅ Automatic formatter detection:

• Prefers xcbeautify → xcpretty → plain output

✅ Color-coded output:

• Warnings in yellow
• Errors in red
• Success in green

Testing

✅ 109 unit tests - All passing
✅ Config file mode - Verbose works from config
✅ CLI override - CLI flags override config settings
✅ Formatter detection - xcbeautify auto-detected
✅ Real-time streaming - Build logs appear as they happen
