Subject: [PATCH 1/4] refactor(grimshot): modularize and clean up with
 functional helpers

- Introduced functional helper methods: `when`, `if_else`, and `any` for cleaner, more maintainable logic.
- Refactored conditional handling in `notifyOk`, `notifyError`, and `check` functions to leverage the new helper methods.
- Moved usage message printing to a dedicated `printUsageMsg` function.
- Extracted subject-specific logic (e.g., area, window, screen) into standalone functions: `selectArea`, `selectWindow`, etc.
- Improved error handling by introducing functions like `handleScreenshotSuccess`, `handleScreenshotFailure`, and `handleSaveCopy`.
- Reformatted code and improved readability by using consistent formatting for case statements and conditions.

This refactor enhances code maintainability by isolating logic into reusable components, improving clarity and simplifying future changes.

- Moved all grim related files to their own directory
- Refactored argument parsing into the `parseArgs` function for improved
clarity.
- Added `handleUnknownSubject` to handle unknown subjects explicitly.

Subject: [PATCH 3/4] fix(grim): handle positional arguments and error message
 in notifyError

- Introduced `POSITIONAL_ARGS` to collect and reassign positional
arguments using `set -- $POSITIONAL_ARGS` after flag parsing, ensuring
correct positional argument handling.
- Ensured flag parsing (`--notify`, `--cursor`, `--wait`) is processed
before positional arguments.
- Stored `$1` as `error_message` in `notifyError` to fix incorrect
reference during condition evaluation.
