Refactor index (#156)

* feat: add Telegram channel with agent swarm support

Add Telegram as a messaging channel that can run alongside WhatsApp
or standalone (TELEGRAM_ONLY mode). Includes bot pool support for
agent swarms where each subagent appears as a different bot identity
in the group.

- Add grammy dependency for Telegram Bot API
- Route messages through tg: JID prefix convention
- Add storeMessageDirect for non-Baileys channels
- Add sender field to IPC send_message for swarm identity
- Support TELEGRAM_BOT_TOKEN, TELEGRAM_ONLY, TELEGRAM_BOT_POOL config

* refactor: extract channel abstraction, IPC, and router from index.ts

Break the 1088-line monolith into focused modules:
- src/channels/whatsapp.ts: WhatsAppChannel class implementing Channel interface
- src/ipc.ts: IPC watcher and task processing with dependency injection
- src/router.ts: message formatting, outbound routing, channel lookup
- src/types.ts: Channel interface, OnInboundMessage, OnChatMetadata types

Also adds regression test suite (98 tests), updates all documentation
and skill files to reflect the new architecture.

* chore: remove accidentally committed pool-bot assets

* fix(ci): remove grammy from base dependencies

Grammy is installed by the /add-telegram skill, not a base dependency.
