Fix handling special chars in script paths

This commit improves the handling of paths with spaces or special
characters during script execution in the desktop application.

Key improvements:

- Paths are now quoted for macOS/Linux, addressing issues with
  whitespace or single quotes.
- Windows paths are enclosed in double quotes to handle special
  characters.

Other supporting changes:

- Add more documentation for terminal execution commands.
- Refactor terminal script file execution into a dedicated file for
  improved separation of concerns.
- Refactor naming of `RuntimeEnvironment` to align with naming
  conventions (no interface with I prefix) and for clarity.
- Refactor `TemporaryFileCodeRunner` to simplify it by removing the `os`
  parameter and handling OS-specific logic within the filename generator
  instead.
- Refactor `fileName` to `filename` for consistency.
