Add comprehensive tests for PathConfidenceScorer, PathEnumerator, ShellSymbolicExecutor, and SymbolicState

Browse Source 
- Implemented unit tests for PathConfidenceScorer to evaluate path scoring under various conditions, including empty constraints, known and unknown constraints, environmental dependencies, and custom weights.
- Developed tests for PathEnumerator to ensure correct path enumeration from simple scripts, handling known environments, and respecting maximum paths and depth limits.
- Created tests for ShellSymbolicExecutor to validate execution of shell scripts, including handling of commands, branching, and environment tracking.
- Added tests for SymbolicState to verify state management, variable handling, constraint addition, and environment dependency collection.
