fix: prevent sensitive data logging (#70)

* feat: Add sensitive data masking to packet logging by introducing a sanitization function and a list of sensitive keys.

* test: mock console methods in logger tests and restore after each test

* refactor: remove redundant sensitive data masking functions and integrate safeStringifyPacket utility for improved logging

* fix: run format:write

* test: enhance logger tests with error handling for directory setup and cleanup

* refactor: optimize sensitive data masking logic by checking for exact matches in sensitive keys

* refactor: enhance sensitive data masking to handle circular references and improve sanitization logic

* refactor: update sensitive data masking comments and test descriptions to improve clarity and consistency

* test: enhance logger tests with dynamic log directory creation and cleanup after tests

* test: add unit tests for handling malformed JSON strings in sensitive data masking
