This PR refactors several parts of the codebase with the following improvements:

• Improved structure and readability: Code layout has been made cleaner and more consistent.
• Removal of unnecessary temporary variables: Simplified logic by eliminating redundant variables in several functions.
• Use of static constants: Replaced magic strings (e.g., "cli") with clearly defined static constants for better maintainability.
• Optimized conditionals: Conditional expressions have been simplified to enhance clarity.
• Enhanced safety: Replaced the use of strlen and strncmp with strncasecmp for more secure SAPI name comparison.
• Maintained logic integrity: All core algorithms and functional logic remain unchanged.
• Concise code: Reduced verbosity by removing redundant structures and streamlining function bodies.

These changes aim to make the codebase easier to maintain, safer, and more readable without affecting existing functionality.
