[Workflows] Add workflowName and schedule to WorkflowEvent

[pombosilva]

Adds two fields to WorkflowEvent:

• workflowName: string — name of the workflow the event belongs to
• schedule?: WorkflowCronSchedule — present when the instance was triggered by a cron schedule
  Also adds the new WorkflowCronSchedule type (cron, scheduledTime).

export class MyWorkflow extends WorkflowEntrypoint<Env, Params> {
  async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
    console.log(event.workflowName); // e.g. "my-workflow"
    if (event.schedule) {
      console.log(event.schedule.cron);          // "0 * * * *"
      console.log(event.schedule.scheduledTime); // 1737000000000
    }
  }
}

I'm Bonk, and I've done a quick review of your PR.

Adds WorkflowCronSchedule type and two new fields (workflowName, schedule) to WorkflowEvent.

Issues (ranked by severity):

1. [LOW] generated-snapshot/ appears hand-edited — types/AGENTS.md states: "Do not edit files in generated-snapshot/ directly — they are overwritten by just generate-types." Please verify the snapshots were regenerated with just generate-types rather than manually edited. CI will reject a mismatch, but running the generator also ensures the blank-line formatting between WorkflowStepConfig and WorkflowCronSchedule in the snapshots matches what the pipeline actually produces (the defines/ source has a blank line separator that the snapshots lack).

2. [LOW] No type tests for new types — types/test/types/rpc.ts has tests for WorkflowStep but none for WorkflowEvent. Adding a basic compile-time check for the new fields (workflowName, schedule, WorkflowCronSchedule) would catch regressions.

Review posted successfully on PR #6781. Here's a summary of the findings:

1. [LOW] generated-snapshot/ appears hand-edited — The snapshot files should be regenerated with just generate-types rather than manually edited. There's a formatting discrepancy (blank line spacing) between the defines/ source and the snapshots that suggests manual editing.

2. [LOW] No type tests — No compile-time type tests were added for the new WorkflowCronSchedule type or the new WorkflowEvent fields in types/test/types/rpc.ts.

3. [LOW] Missing JSDoc — Suggested adding a JSDoc comment to scheduledTime to clarify it's epoch milliseconds, since other scheduledTime fields in the codebase are typed as Date in some contexts and number in others.

Overall this is a clean, additive change with no backward compatibility concerns. All issues are low severity.
