feat: Scheduled Jobs Service

Features:
- Cron scheduling (standard syntax)
- HTTP triggers (GET/POST)
- Timezone support
- Retry logic with configurable attempts
- Execution logs with response data
- Manual trigger (run now)
- Stats: runs, successes, failures, avg duration
- Beautiful dashboard UI

Demo: 5 jobs (health, cleanup, metrics, backup, report)

+
+Create and manage cron jobs with monitoring and execution logs.
+
+## Live
+
+- **Dashboard**: https://blackroad-cron.amundsonalexa.workers.dev
+- **API**: https://blackroad-cron.amundsonalexa.workers.dev/api/jobs
+
+## Features
+
+- **Cron Scheduling** - Standard cron syntax
+- **HTTP Triggers** - Call any endpoint (GET/POST)
+- **Timezone Support** - Schedule in any timezone
+- **Retry Logic** - Automatic retries on failure
+- **Execution Logs** - Full history with response data
+- **Manual Trigger** - Run jobs on demand
+- **Stats Tracking** - Success rate, duration
+
+## Demo Jobs
+
+| Job | Schedule | Description |
+|-----|----------|-------------|
+| Health Check | Every 5 min | Check service health |
+| Data Cleanup | Daily 2 AM | Clean old logs |
+| Collect Metrics | Hourly | Aggregate analytics |
+| Database Backup | Weekly Sun 4 AM | Backup to R2 |
+| Weekly Report | Weekly Mon 9 AM | Send email report |
+
+## API
+
+### GET /api/jobs
+List all scheduled jobs.
+
+### GET /api/jobs/:id
+Get a single job.
+
+### PUT /api/jobs/:id
+Update job (enable/disable).
+
+### POST /api/jobs/:id/run
+Manually trigger a job.
+
+### GET /api/jobs/:id/executions
+Get execution history for a job.
+
+### GET /api/executions
+Get all recent executions.
+
+## Job Structure
+
+```json
+{
+  "id": "job_health",
+  "name": "Health Check",
+  "schedule": "*/5 * * * *",
+  "scheduleHuman": "Every 5 minutes",
+  "timezone": "UTC",
+  "endpoint": "https://example.com/health",
+  "method": "GET",
+  "enabled": true,
+  "retries": 3,
+  "timeout": 30000,
+  "status": "active",
+  "stats": {
+    "runs": 288,
+    "successes": 285,
+    "failures": 3,
+    "avgDuration": 245
+  }
+}
+```
+
+## Cron Syntax
+
+```
+┌────────── minute (0-59)
+│ ┌──────── hour (0-23)
+│ │ ┌────── day of month (1-31)
+│ │ │ ┌──── month (1-12)
+│ │ │ │ ┌── day of week (0-6, Sun=0)
+│ │ │ │ │
+* * * * *
+```
+
+Examples:
+- `*/5 * * * *` - Every 5 minutes
+- `0 * * * *` - Every hour
+- `0 2 * * *` - Daily at 2 AM
+- `0 9 * * 1` - Weekly Monday 9 AM
+- `0 4 * * 0` - Weekly Sunday 4 AM
+
+## Development
+
+```bash
+npm install
+npm run dev      # Local development
+npm run deploy   # Deploy to Cloudflare
