feat(events): an event action's progress() on a live run's public page (MODULE_API 1.12.0)
An event action may declare an optional `progress(envelope)`: how its
step stands while the run is live. Core accepts two shapes and
interprets neither:

- a count: { label, left, of }, rendered "Bandits: 3 of 8 left";
- a percentage: { label, percent }, rendered "The Juggernaut: 62%".

How core asks:

- `events/progress.js` asks each step of a live run whose action has
  one. It passes the step's own held ledger rows and the reader's
  account id, so the module applies its own visibility.
- Each call has a 2 s deadline. A throw, a late answer or any other
  shape is a line not shown, never an error on the page.
- One answer per run and reader is cached for 5 s.
- The public event's live occurrence carries the lines as `progress`.
  The route takes an optional session for the reader.
- The page renders them under the phase label and re-reads them every
  15 s while the event is live.

Core stays game-agnostic: no game's words are in it. Additive, so a
minor bump. Module-uo declares ^1.10.0, registers no action with
progress(), and its actions and pages are unchanged.

From RunicNPC stage 8 (D304, D305).
