fix(cron): include model/provider in deploy comparison

Fixes #375

_jobs_changed() compares prompt, schedule, model, and provider.
Model/provider-only YAML changes are no longer silently dropped.

-deploy-crons — normalize cron job schemas for consistent model field types.
+deploy-crons -- deploy cron jobs from YAML config and normalize jobs.json.
 
-This script ensures that the model field in jobs.json is always a dict when
-either model or provider is specified, preventing schema inconsistency.
+Two modes:
+  --deploy     Sync jobs from cron-jobs.yaml into jobs.json (create / update).
+  --normalize  Normalize model field types in existing jobs.json.
+
+The --deploy comparison checks prompt, schedule, model, and provider so
+that model/provider-only changes are never silently dropped.
 
 Usage:
-    python deploy-crons.py [--dry-run] [--jobs-file PATH]
+    python deploy-crons.py --deploy   [--config PATH] [--jobs-file PATH] [--dry-run]
+    python deploy-crons.py --normalize [--jobs-file PATH] [--dry-run]
