refactor(console-catcher): convert to class with singleton pattern

[Dobrunia]

Changes:

• Converted createConsoleCatcher() factory function to ConsoleCatcher class
• Implemented singleton pattern via static getInstance() method
• Moved internal state (consoleOutput, isInitialized) to private class fields
• Converted all internal functions to private/public class methods
• Integrated ConsoleCatcher into Catcher class via instance property
• Replaced direct function imports with class instance usage in catcher.ts

Benefits:

• Better code organization and encapsulation
• Easier to test and maintain
• Consistent with other class-based modules in the codebase
• Preserves all existing functionality without breaking changes
