Hashing and automatic indexing for V3

[jpwilliams]

Summary

Adds hashing of step IDs, meaning step IDs passed between the SDK and Inngest are never plain text and of consistent length.

Adds automatic indexing of steps to avoid common uses of step tooling within loops and parallelism. The following example would set the step IDs to A, A:1, and A:2.

const runA = () => step.run("A", () => "result");

await Promise.all([runA(), runA(), runA()]);

Adds a new error code, AUTOMATIC_PARALLEL_INDEXING, which warns if these indexes are added across parallel chains of work, which is harder for the SDK to reason about in V3.
