feat(config): add shorthand syntax for schedule, run, build, and log

Support both string and object forms for cleaner simple configs:

- schedule: "*/5 * * * *" instead of schedule: { cron: "..." }
- run: "./app" instead of run: { sh: "..." }
- build: "cargo build" instead of build: { sh: "..." }
- log: "output.log" instead of log: { file: "..." }

Full object form still available when additional options needed.
