v0.5.0

Added

• A message set aside for the morning can now expire: not very important after
  2 h, normal after 12 h, important never. Change it for the household on the
  new How long a message set aside stays useful step, or for one call with
  data.ttl_minutes (0 means "keep this one whatever the household says").
  An expired message is dropped with the new reason expired, instead of
  announcing at 07:00 that the front door was open at 23:31.
• One summary instead of a burst. When more than one message survives the night
  for somebody, they get a single notification per device listing them, rather
  than eleven banners at the moment they open their eyes. Turn it off per person
  with Sum it all up in one message.
• A back-to-normal message now reaches only the people who actually received
  something for that alert; everybody else is dropped with the new reason
  not_notified. Mark your own back-to-normal call with
  data.switchboard_done: true.
• Every message gets a name (data.tag, switchboard-<slug> by default), so a
  repeat updates the notification already on the phone instead of stacking a
  second one. A tag you set always wins.
• When a watched alert ends, the notifications it left on each phone are cleared
  and the matching dashboard notification is dismissed. The new target setting
  Clear the back-to-normal message extends that to the back-to-normal
  message itself. This applies to targets in observer mode only.

Changed

• A message released in the morning is decided again from scratch: somebody who
  left the house under a home_only target is dropped on presence, somebody who
  snoozed at 02:00 is dropped as snoozed, a deleted target drops the lot. Its
  original importance is kept, so a target whose default changed overnight
  cannot silently re-grade it.
• A queue is flushed as soon as the last silence turns off, instead of waiting
  for the wake time. Somebody with both a night schedule and a Focus sensor
  needs both off; the wake time stays the upper bound.
• sensor.switchboard_dropped_today gains expired and not_notified in its
  reasons attribute. No new event type.
• Upgrading migrates the stored snoozes and deferrals; nothing to do by hand.
