Since we're moving to server side serialized ids, we dont need to
simulate the prior model.
## Summary
- remove the mint-ordered simulation mode and reservation API
- make commit-time log positions and lagging-prefix reads the only
simulator behavior
- simplify CI, scenarios, tests, and documentation to the single log
model
## Testing
- node --check on changed TypeScript files
- pnpm --filter @workflow/world-sim test (blocked: node_modules is
absent; vitest unavailable)
