Package cron parses a task's schedule — a 5-field cron expression, an "@every <duration>" interval, or a named shorthand (@daily, @hourly, …) — into a Schedule that yields the next fire time.

Package penv builds the environment for a project's build and service processes: the daemon's own environment, the NEXUS_* contract variables, volume paths (the unit's own plus every known project's, for cross-project wiring), an optional .env file, and docker-compose-style environment: maps with ${VAR} interpolation.
