waybill 2.1.1

First field report from a 3.4B-token ledger, same day. Ledgers metered by
pre-1.x engines carry zero-token usage events under the placeholder model
id <synthetic> (the current parser skips such messages at the source,
so the events are historical and — append-only — permanent).

Fixed

• Zero-token placeholder models no longer poison pricing health —
  status and pricing show named <synthetic> as an unpriced model
  with a pricing set "fix" that would invent a rate for a non-model;
  and once any rate resolved for it, status counted its events as
  "metered before their rate existed — re-price: waybill meter --all",
  advice that is permanently unfollowable (the meter never re-emits
  zero-usage grains, so no superseding event can ever exist). Models are
  now drawn only from events that actually carry tokens
  (meteredModels, the same principle as the long-standing "unknown"
  exclusion), and the no-cost / re-priceable counts skip zero-token
  events. The status wording also scopes itself honestly: "their costs
  stay tokens-only", not the ledger's.

Added

• waybill dashboard opens the page it wrote — users shouldn't need
  to know how to open an HTML file. The explicit command launches the
  default browser (macOS open, Windows start, else xdg-open),
  best-effort and detached; --no-open skips it, --json never
  launches, and the miner's silent refresh path is untouched — a
  browser must never pop because a session ended.
