feat(fitness): classify exercises by type and redesign filter UI

Distinguish stretches, strength, cardio, and plyometric exercises
with a curated `exerciseType` field that overrides mislabels in
ExerciseDB for the hand-curated stretch set. Surface the type as
pills on the detail page and as a filter toggle on the list page.

Replace the muscle-group and equipment dropdowns with horizontally
scrolling pill rows; equipment pills carry Lucide icons, and the
type toggle shows a flexed-bicep / person / layers glyph. Selected
muscle groups hoist to the front of the scroller.
