Logger abstraction added

[Reversean]

Related #151

Added env-agnostic Logger abstraction.

Also added global singleton loggerInstance which could be set via setLogger and used via log methods.

Also added browser-specific logger factory-method createBrowserLogger which may be used as Logger.

Pull request overview

This PR introduces an environment-agnostic logger abstraction to support the architectural refactoring described in issue #151. The implementation separates core logging functionality from browser-specific implementation details, setting the foundation for a cleaner package structure that will enable code reuse across different JavaScript environments (Node.js, Nuxt, etc.).

Changes:

• Added core logger abstraction (Logger interface, LogType, setLogger(), log()) to @hawk.so/core
• Migrated browser-specific logger from utils/log.ts to logger/logger.ts as a factory function
• Updated all imports across the codebase to use the new logger from @hawk.so/core
