maintenance: ESLint, Prettier, Husky

[rbonestell]

This pull request includes several changes to improve code quality and maintainability, particularly focusing on ESLint configuration, code formatting, and test improvements. The most important changes include the migration to a new ESLint configuration file, and updates to the .prettierrc file.

ESLint and Prettier Configuration:

• Migrated from .eslintrc.js to eslint.config.mjs for a modern and modular ESLint configuration. This includes importing necessary plugins and defining default configurations.
• Updated .prettierrc to use tabs for indentation and set the trailingComma option to es5.

Code Formatting and Linting:

• Added a pre-commit hook to run linting on staged files using Husky and lint-staged.
• Enhanced VSCode settings to enforce consistent code formatting and linting rules, including enabling ESLint and Prettier extensions.

Improvements to LocalHttpsProxy:

• Renamed LocalHttpsProxy interface to ILocalHttpsProxy to disambiguate with the LocalHttpsProxy class.

Package Configuration:

• Added new scripts and dependencies in package.json to support the new linting and formatting setup.
