## Summary
- Removes the per-step `canBillMeteredProduct(WORKFLOW_NODE_EXECUTION)`
gate in `WorkflowExecutorWorkspaceService.executeStep` so workflows keep
running when a workspace reaches `hasReachedCurrentPeriodCap`.
Previously every step failed with
`BILLING_WORKFLOW_EXECUTION_ERROR_MESSAGE` (\"No remaining credits to
execute workflow…\").
- Drops the now-unused `BillingService` injection, related imports, and
the helper `canBillWorkflowNodeExecution`. Updates the spec to drop the
corresponding billing-validation case and mock.
- Leaves the constant file and `BillingService` itself in place, plus a
TODO at the previous gate site, so the behavior can be re-enabled with a
small, reviewable revert.
## Notes
- Usage events are still emitted (`USAGE_RECORDED` /
`UsageResourceType.WORKFLOW`), and `EnforceUsageCapJob` keeps computing
the cap and flipping `hasReachedCurrentPeriodCap` — only the executor
stops consulting that flag.
- The runner-level `canFeatureBeUsed` check in
`WorkflowRunnerWorkspaceService.run` was already log-only (subscription
presence, not credits), so no change there.
- AI chat (`agent-chat.resolver.ts`) keeps its own
`BILLING_CREDITS_EXHAUSTED` gate; this PR does not touch it.
## Test plan
- [x] `npx jest workflow-executor.workspace-service.spec.ts` (17/17
pass)
- [ ] Manual: with billing enabled and the metered subscription item
flagged `hasReachedCurrentPeriodCap = true`, trigger a workflow run and
verify steps execute end-to-end instead of failing with the billing
error.
