fix: add Git error handling and directory recovery for workspace issues

GIT ERROR HANDLING FIX: Resolve 'Unable to read current working directory' errors

Issues Fixed:
❌ fatal: Unable to read current working directory: No such file or directory
❌ Git operations failing due to directory issues
❌ Insufficient Git status checking before operations
❌ Missing Git error recovery mechanisms

Root Cause:
- Git unable to access current working directory
- Directory permissions or filesystem issues
- No Git status validation before operations
- Missing error recovery for Git directory problems

Solution Applied:
✅ Enhanced Git status checking and validation
✅ Directory recovery mechanisms for Git errors
✅ Improved error reporting and debugging
✅ Git operation testing before clone attempts

Git Error Handling Improvements:
1. Git Status Validation:
   - Test git status before operations
   - Directory recovery if Git fails
   - Root directory fallback strategy
   - Return to workspace after recovery

2. Enhanced Debugging:
   - Git version and configuration display
   - Current directory contents listing
   - Filesystem permissions check
   - Step-by-step operation reporting

3. Error Recovery:
   - Change to root directory if Git fails
   - Return to workspace after recovery
   - Multiple directory change attempts
   - Graceful error handling

4. Operation Validation:
   - Test Git operations before clone
   - Validate directory accessibility
   - Check filesystem status
   - Provide detailed error information

Impact:
- Git operations now work reliably
- Better error recovery for directory issues
- Enhanced debugging information
- Robust workspace setup
- Reliable CI/CD execution

This resolves the critical Git directory access issues that were
preventing package tests from setting up the repository properly.
