v0.17.2

Added

• daemon.PublicationSlot.Value resolves the exact resource graph carried by
  an already-admitted request while its admission lease remains live, without
  opening a nested admission or consulting the runtime's current publication.

Fixed

• Re-prove exact dedicated-session absence when Darwin reports EPERM for a
  signal raced by natural process-group exit, while retaining ownership if any
  member remains.
• Make the Swift broker-handoff deadline test prove delivery to a still-blocked
  peer without assuming a wall-clock scheduler-latency bound.
