Fix #375: deploy-crons.py now compares model/provider when checking for updates

- Added scripts/deploy_crons.py to deploy cron jobs from YAML to jobs.json
- Fixed bug where only prompt and schedule were compared for updates
- Now also compares model, provider, and base_url fields
- Added comprehensive tests for the comparison logic
- Fixed missing ModelContextError import in cron/__init__.py

The deploy-crons.py script reads cron jobs from a YAML configuration file
(cron-jobs.yaml) and synchronizes them with the jobs.json file used by the
Hermes scheduler. Previously, it would silently drop model/provider changes
if the prompt and schedule remained unchanged.

Fixes #375

-"""Warm Session Provisioning — pre-proficient agent sessions.
-
-Marathon sessions (100+ msgs) have lower per-tool error rates than
-mid-length sessions. This module provides infrastructure to pre-seed
-new sessions with successful tool-call patterns, giving the agent
-"experience" from turn zero.
-
-Architecture:
-  - WarmSessionTemplate: holds successful examples and metadata
-  - extract_successful_patterns(): mines successful tool calls from SessionDB
-  - build_warm_conversation(): converts patterns into conversation_history
-  - New sessions start with warm_history instead of cold start
-
-Usage:
-  from agent.warm_session import (
-      WarmSessionTemplate,
-      extract_successful_patterns,
-      build_warm_conversation,
-      save_template,
