jobs.rs

//! Job scheduler — replaces `jobs_tick.sh`.
//!
//! Reads job definitions from `jobs.yml`, checks cron schedules against
//! the current time, and creates tasks for due jobs. Handles catch-up
//! for missed schedules (capped at 24h).
//!
//! Job types:
//! - `task`: creates a task (GitHub Issue or internal SQLite) and lets the engine dispatch it
//! - `bash`: runs a shell command directly (no LLM)
//! - `self-review`: analyzes task metrics and creates self-improvement issues
//!
//! For task jobs, the `external` field controls where the task is created:
//! - `external: false` (default): Creates an internal SQLite task
//! - `external: true`: Creates a GitHub Issue
