v0.9

Features:

• Double-click to edit a section
• Enable Firestore persistence (offline + caching)
• Load more steps at a time, and start loading before reaching the top

Fixes:

• Fix the behavior of the editor
  • Inserts a separator when collapsing a bullet
  • Adding a new line before a separator creates a new bullet and removes that separator
  • Working copy/paste
  • Regarding trailing spaces, automatically insert a space after the end-of-thought separator, but don't save it into the database
• <yo be real> tag can be edited for action and outcome, modifying other sections if necessary
