v0.29.0

Highlights

• A pending authority-store migration can no longer strand a lane. The
  server shuts down when the shared authority store moves ahead of it, agents
  refuse to start while a migration is pending, and lanes that a pending
  migration would strand are refused work up front rather than after the
  fact. The migration contract now has an accepted design record.
• Task phases finish correctly when integration moves the checkout. Phase
  completion reloads in the checkout the landing selected, and both
  continuation arms derive their identity from durable claim and review state
  instead of carrying it on the wire. When a continuation does fail, the
  landing stays authoritative and the recovery command pins the checkout it
  must run under and names the shell that can run it.
• A durable write no longer reports itself as a failure. spice task done
  reports what landed instead of exiting 2 after the phase advance, and
  spice task review's post-write presentation goes through that same
  landed-work boundary.
• rtk declines rg rewrites it cannot answer faithfully. A rewrite that
  would change the search dialect under the caller, or forward an rg-only flag
  to grep, is now declined rather than silently reinterpreted — and the health
  probe measures that a rewrite preserves the answer.
• Sticky gate ledgers stop latching on runs that were never accepted.
  File-loc ledgers persist only for a commit the gate actually accepted, and
  failure text names a stale latch so the remedy is discoverable.
• Scheduling and landing repairs. Phase advance un-defers the task whose
  claim it releases, task doctor names a waiting task that strands its
  pending dependents, and landing recovery distinguishes accidental
  restoration from intentional ownership.
• Serve browser lifecycle readiness budgets raised from 20s to 30s, and
  subsumption recording now runs in the project test runtime so it works from
  a disposable checkout.
