refactor: replace logger with console statements in subprocess management

- Removed the centralized logging system in favor of direct console.log and console.error statements for subprocess management.
- Updated logging messages to include context for subprocess actions, such as spawning commands, handling errors, and process completion.
- This change simplifies the logging approach in subprocess handling, making it easier to track subprocess activities during development.
