Derive the deterministic RNG seed from `runId:workflowName:deploymentId` and the VM's initial fixed clock from the ULID timestamp embedded in `runId` (via the new `runIdCreatedAt` helper). All of these inputs are available the instant a queue message arrives, so the VM seed and clock no longer depend on `startedAt` (set only after the `run_started` round-trip). This is the prerequisite for starting VM initialization earlier on the critical path. This changes the seed-derived value sequence for a given run, so the affected deterministic test fixtures are regenerated accordingly.

Derive the workflow VM's deterministic RNG seed from runId:workflowName:deploymentId (instead of including the run's startedAt) and its initial fixed clock from the ULID timestamp embedded in runId. These inputs are all available the moment a queue message arrives, decoupling VM setup from the run_started round-trip. Note: this changes the seed-derived value sequence (step/hook correlation IDs, nanoids, random values) for a given run, so runs started before this change must not be replayed across the upgrade.
