Enhance Footholds with Types

[aymswick]

Footholds are items in a Zone that a user can "grab onto" when they are feeling unsure of what to do next. We probably need several types of footholds to account for different interaction expectations:

• Chore: repeating checklist items, count and disappear tap action
• Boost: reminder to give yourself something nice, environment UP tap action (play spotify music)
• Pause: placeholder for meditative time environment DOWN action, prompted to view meditation animation or read a book etc
• Contribution: any effort toward a larger, long-term effort (job, project, hobby, school) with progress / goal / time log tap action
