v0.0.2 - stale beacons fix

Fixes for stale beacon links and a side panel that showed a live
connection count against a node that was not running.

• beacon: relayed connections are no longer capped at 2 min / 128 KiB,
  reservations are released on disconnect, and a peer whose reservation
  expired under a live connection is hung up so it re-reserves.
• net: repair a beacon link when its inbound half is dead (connected but
  subscribed to no CT topic), not only when our own outbound stream is
  gone; wait between hang-up and re-dial so gossipsub rebuilds streams.
• extension: start the node when a fresh offscreen document appears, and
  report offline the moment its port dies instead of freezing the last
  live status.
