Prompt: Using the existing schema and auth, build the exercise library: a page listing exercises from the exercises table with search and filter by exercise_type and primary_muscle. Add a form for users to create a custom exercise (sets is_custom=true and created_by to the logged-in user). Show a visual badge distinguishing custom vs. pre-built exercises in the list.

Pull the pre-existing exercise list from Github
