⚙️ Automation Hub — Notification Dispatcher Demo

• Multi-channel dispatch — Email (SMTP), Slack webhooks, HTTP webhooks, SMS gateways, console
• Template rendering — Python `string.Template` placeholders in messages
• Priority levels — `low`, `normal`, `high`, `critical` with per-channel routing
• Retry with backoff — Exponential backoff on delivery failures (3 retries default)
• Delivery logging — Track every send attempt in SQLite
• Batch dispatch — Send multiple notifications from a single config file

# Send a quick email
python src/notification_dispatcher.py --channel email \
    --to user@example.com --subject "Alert" --message "Server CPU at 95%"

# Send a Slack notification
python src/notification_dispatcher.py --channel slack \
    --to "#ops-alerts" --message "Deploy complete" \
    --webhook-url https://hooks.example.com/services/T00/B00/xxx

# Send a webhook notification
python src/notification_dispatcher.py --channel webhook \
    --to https://api.example.com/v1/alerts --message '{"event": "deploy"}'

# Batch dispatch from config
python src/notification_dispatcher.py --config examples/notifications_config.json
