Implement verbose error feedback across all scripts

- Enhanced die() function with environment context and stack trace
- Added detailed error output with line numbers and file paths
- Improved check_dependencies with installation guides
- Enhanced PHP syntax validation with full error details
- Added verbose error messages to manifest, tabs, and paths validations
- Updated validate_all to show error summaries (full output in verbose mode)
- Updated smoke_test with detailed PHP error reporting
- Updated ENTERPRISE.md with verbose error examples
- All error messages now provide actionable troubleshooting steps
