Resonate Durable Sleep + Scheduled Work — Rust

SDK note (0.6.0). The Rust SDK is in active development. This skill covers two features in the current release: ctx.sleep(Duration) for in-workflow durable sleep, and resonate.schedule(name, cron, fn, input) for cron-registered ephemeral-world scheduling. (Note: the Python SDK does not yet expose a top-level schedule(); Rust does.)

Overview

Two related but distinct capabilities:

1. Durable sleep inside a workflow — ctx.sleep(Duration) pauses execution; the worker process is free to exit and resume days later without the sleep "losing its place."
2. Cron-scheduled invocation from the ephemeral world — resonate.schedule(...) registers a function to fire on a cron schedule until explicitly deleted.

Both are Rust-idiomatic — Duration for in-workflow time, cron strings for cron schedules. Both are durable; Resonate holds the continuation in its store, not in a long-running process.
