simplified code

Reductions:

~170 lines → ~110 lines (35% fewer lines)
Removed unnecessary functions and constructors
Combined structs and simplified JSON parsing
Streamlined error handling
Merged sendRequest and SendMessage into single Send method

Key simplifications:

Used inline struct definitions for Response parsing
Replaced Metadata struct with simple map[string]string
Removed NewMessenger constructor - use struct literal directly
Inlined the header printing
Simplified constant names (colorBlue → blue)
Reduced verbose error messages

The app works exactly the same but with much cleaner, more maintainable
code! All features are preserved:

 Colorized input/output
 Arrow key history navigation
â Conversation context tracking
 Same API communication
