v1.2.0 - Bug fixes and updated error output format

Added

• GNU Standard Error Format: Error messages now include filename and line numbers
  • Configurable via gnu_error_format = true/false (default: true)
• Configurable Error Message Line Wrapping: Control line wrapping
  • Can be enabled for terminal-friendly wrapped output

Changed

• The != operator is correctly preserved as !=
  • No unwanted space insertion in shell comparison operators
  • Regular Make assignments still get proper spacing
• Place .PHONY after file header but before section comments
• Conditional targets properly excluded
  • default and build targets inside conditionals are no longer included in .PHONY
• Non-conditional targets properly included (clean, install, test targets outside conditionals)
• Normalized tab indentation for consistency in edge-cases (e.g., mixed tabs+spaces)
• Added context param to format method in base.py for passing references to any rule (e.g., original .mk content)
