fix: Change unifySameTitleSession default value to false (#48)

* refactor: Clean up message handling in ClaudeCodeLifeCycleService

- Removed debug logging from handleMessage function.
- Eliminated unnecessary fallback message check in message iteration loop.

This improves code readability and performance by streamlining message processing.

* fix: Change unifySameTitleSession default value to false

Changed the default value of unifySameTitleSession configuration from true to false.
This affects both the Zod schema definition and the UserConfigService initial state.

Updated README.md to reflect the new default value in the User Settings table.
