v0.7.2

Fixed

• Deleted-session suppression survives eviction: an id evicted from the bounded
  deleted window could be resurrected by a late step-finish, re-counting spend
  already folded into its parent. Deleted ids are now also recorded in a
  fixed-size filter with no false negatives, and a live-entry check lets a
  restarted session.created through. Adds the seeded usage-ledger invariant
  suite (test/budget-state.invariants.test.ts) covering the eviction
  regression.
