Ignite Notify – Real-time Blockchain Event Notification App

[QuenumGerald]

This PR introduces Ignite Notify, a standalone application designed for the Cosmos SDK ecosystem. Ignite Notify lets you subscribe to blockchain events from any Tendermint-based node and receive real-time notifications in your favorite channels—Telegram, Slack, and more.

Key Features

• Flexible event subscriptions: Monitor any Tendermint/Cosmos event using custom queries (e.g., tm.event EXISTS).
• Multi-channel delivery: Send notifications to Telegram, Slack, or stdout. Easily extendable to other platforms.
• YAML-based persistent configuration: Manage all your subscriptions declaratively.
• Automatic WebSocket reconnection: Robust event streaming from your node.
• Command-line interface: Add, list, remove, and run subscriptions with intuitive CLI commands.
• User-friendly, flat notifications: Events are formatted as flat key:value pairs, with technical prefixes removed for clarity.
• Open source (Apache 2.0): Built for the community and extensibility.
