feat: add Logger utility for controlled console output

- Introduced a Logger class to manage logging behavior based on the environment (production or development).
- Replaced console.log, console.warn, and console.error calls throughout the codebase with Logger methods to ensure consistent logging.
- Updated various modules including main.ts, markdown-it-image-plugin.ts, oauth2-client.ts, and others to utilize the new Logger class for improved logging practices.
