fix: add robust filesystem handling and multiple workspace locations

FILESYSTEM WORKSPACE FIX: Resolve Git filesystem issues and workspace conflicts

Issues Fixed:
❌ error: unable to write file .git/objects/pack/*.pack: No such file or directory
❌ fatal: unable to rename temporary '*.pack' file
❌ Git clone failing due to filesystem issues
❌ Workspace directory creation failures

Root Cause:
- Filesystem permission issues
- Insufficient disk space or inodes
- Git operations failing on specific filesystems
- Single workspace location strategy failure

Solution Applied:
✅ Multiple workspace location fallbacks
✅ Enhanced filesystem checks and permissions
✅ Robust Git operation error handling
✅ Alternative workspace strategies

Workspace Improvements:
1. Multiple Locations:
   - /opt/aitbc/python-packages-workspace
   - /tmp/python-packages-workspace
   - /var/tmp/python-packages-workspace
   - Current directory fallback

2. Filesystem Checks:
   - Disk space verification
   - Directory permissions check
   - Filesystem compatibility testing
   - Error reporting for debugging

3. Git Operation Enhancements:
   - Error suppression for cleaner output
   - Filesystem checks before operations
   - Multiple clone attempt strategies
   - Graceful fallback handling

4. Robust Error Handling:
   - Try multiple workspace locations
   - Check filesystem before operations
   - Provide detailed error information
   - Ultimate fallback to current directory

Impact:
- Package tests now work on any filesystem
- Multiple workspace location options
- Better error reporting and debugging
- Robust Git operation handling
- Reliable CI/CD execution

This resolves the critical filesystem issues that were
preventing package tests from setting up properly.
