Diffo 0.12.0

Diffo 0.12.0 redesigns the layer card and gives the agent chip the companion's face: the companion now lives in the chip.

Changed

• The layer card is composed, not stacked. A meta row carries where the
  step sits and the card's one action; the title and summary follow; the
  decisions run under them as a ledger the width of the card, each row
  opening on a chevron like a file header. Comment on this layer moved
  from the card's foot to its corner, and the rule under the card appears
  only when there is a thread to show or one being written.
• The agent chip wears the companion's face. The chip's three-bar meter
  is gone; the companion's face sits in its place, and the label says the
  state as a verb with the detail muted beside it: Invite your agent,
  Listening, Reading the change, Working on db.ts:42, Paused,
  Suggests layers. A batch in flight fills the pill amber with its n/N
  instead of a separate bar, and the face hops when the batch is answered,
  even with the companion switched off. The companion now lives in the chip:
  it hops out onto the header when you settle or the agent gets to work, and
  back in when you type, a batch is done, or no agent is attached. Reduced
  motion, or a header too narrow to walk, keeps it home.
