Writes, replaces or clears the user's own note on ONE exercise — any exercise, built-in or custom. The note is a short personal cue for the gym floor ("pin 6, seat 4", "bench at 30°, pause on the chest", a link to a video); the Reps app shows it on the exercise and under the exercise during a workout. It is not the how-to: step-by-step instructions for a custom exercise go in `notes` on `update_custom_exercise`. Find the slug with `get_exercise_library`, which also returns the current `note`. `note` replaces the whole note, so to add to it send the old text plus the new; an empty `note` clears it. Applied at once — no confirmation step — so use it when the user asks for the note or has just agreed to it, and say in one sentence what the note now says.
