Minor additions to Makefile

[amito]

Fixes:

1. Make sure ruff exists before trying to run it. Fixes minor issues in the lint and format Makefile targets where we always printed out "ruff is not installed".

New features:

1. Add a typecheck Makefile target which runs mypy.

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title 'Minor additions to Makefile' is vague and generic, using non-descriptive language that doesn't clearly convey the specific changes made (adding typecheck target and fixing conditional ruff execution).	Use a more specific title that highlights the main changes, such as 'Add typecheck target and fix conditional ruff execution in Makefile' or 'Add mypy typecheck target and guard ruff commands in Makefile'.
