Built-in BotFather (Rust, server-side):
- Intercepts messages to @botfather in deliver_or_queue
- Commands: /newbot <name>, /mybots, /deletebot <name>, /token <name>
- Creates bot with fingerprint, token, alias, tracks ownership
- Replies via push_to_client or queue (works offline)
- Only active when --enable-bots is set
Standalone BotFather (Python):
- tools/botfather.py: uses bot API (getUpdates/sendMessage)
- Delegates core ops to built-in handler
- Extensible for additional features
- Reads token from BOTFATHER_TOKEN env or .botfather_token file
Flow: User messages @botfather → "/newbot MyBot" → gets token back

Server:
- DedupTracker in AppState: bounded HashSet (10,000 IDs, FIFO eviction)
- send_message: extracts message ID from bincode, drops duplicates
- WS handler: dedup on both binary and JSON message frames
- extract_message_id() parses all WireMessage variants

Server:
- WS endpoint: /v1/ws/:fingerprint
- Connection registry in AppState (fingerprint → WS senders)
- On connect: flushes queued DB messages, then pushes in real-time
- send_message: pushes to WS if connected, falls back to DB queue
- Auto-cleanup on disconnect
- WS accepts both binary and JSON text frames for sending
Web client:
- Replaces 2-second HTTP polling with persistent WebSocket
- Auto-reconnects on disconnect (3-second backoff)
- Sends via WS when connected, HTTP fallback
- Messages arrive instantly (no polling delay)
- "Real-time connection established" shown on connect
HTTP polling still works:
- CLI recv command uses HTTP (unchanged)
- Web falls back to HTTP if WS fails
- Mules/scripts can still use HTTP API
