LemonChannels provides channel plugins and outbox for message delivery.

This app is responsible for:

• Channel plugin registration and discovery
• Outbound message delivery with retry and rate limiting
• Deduplication to prevent duplicate messages
• Chunking for long messages
• Telegram adapter (and future channel adapters)

Plugin System

Channels are implemented as plugins that implement the LemonChannels.Plugin behaviour. Each plugin provides:

• normalize_inbound/1 - Convert raw channel data to InboundMessage
• deliver/1 - Send outbound payloads to the channel
• gateway_methods/0 - Control plane methods for the channel
