Areev 1.0.1

Fixed

• areev run wave determinism. The driver fed effect completions to
  the pure scheduler in racy arrival batches, each with its own clock
  reading — scheduler state depended on thread timing (an unjournaled
  decision), so two identical runs could checkpoint differently and
  areev run verify could diverge from a live run under load. The driver
  now drains every dispatch wave fully and feeds one close reading plus
  all resolutions in dispatch order — exactly the cadence verify
  replays. Journal-answered replays join the same wave rather than
  resolving early.
• Windows --tool-cmd. /bin/sh was hardcoded in the host tool
  executor and the eval seam; both now use the platform shell
  (cmd /C on Windows).
• areev-run-core purity gate. Dropped the workspace's only chrono
  use (a created_at fallback in canonical serialization, now
  std::time), so the CI gate that keeps clock/rand/IO out of the pure
  scheduler's dependency tree actually passes.
