Compose Linter Parser - Jetpack Compose code quality and best practices analyzer.

The Compose Linter (part of Compose Compiler) provides analysis of Jetpack Compose
code, including recomposition warnings, performance issues, and best practices.

Compose Linter features:
- Recomposition tracking and warnings
- Memoization recommendations
- Composable function analysis
- Parameter stability analysis
- Performance metrics
