feat(features): add channel-to-chat bridge for real-time messaging

Implement a bridge for connecting channel bot conversations (Slack, Discord, Telegram) to the Chat UI. This feature includes message broadcasting, history persistence, and dedicated session handling for each channel. Documentation has been added to describe the architecture and performance characteristics.

+# Channel-to-Chat Bridge
+
+Bridge channel bot conversations (Slack, Discord, Telegram) into the Chat UI in real-time.
+
+## Architecture
+
+```mermaid
+sequenceDiagram
+    participant PU as Platform User
+    participant Bot as SlackBot / DiscordBot / TelegramBot
+    participant Bridge as _attach_chat_bridge()
+    participant CM as ChatManager.broadcast()
+    participant WS as Chat WebSocket (/api/chat/ws)
+    participant UI as chat.js (Chat View)
+
+    Note over Bridge: Attached BEFORE bot.start()
+    Note over Bridge: All broadcasts via asyncio.create_task<br/>(fire-and-forget, zero perf impact)
+
+    PU->>Bot: "Hello" (platform message)
+    Bot->>Bridge: on_message hook fires
+    Bridge->>CM: broadcast({type: "channel_message", ...})
+    CM->>WS: send to connected clients
+    WS->>UI: _handleChannelMessage() renders with platform badge
+
+    Bot->>Bot: agent processes message
+    Bot->>Bridge: _wrapped_chat() returns response
+    Bridge->>CM: broadcast({type: "channel_response", ...})
+    CM->>WS: send to connected clients
+    WS->>UI: _handleChannelResponse() renders as assistant
+```
+
+## How It Works
+
+### Backend (`channels.py`)
+
+`_attach_chat_bridge(channel_id, bot, platform)` is called in `_start_channel_bot()` right before the bot task is launched:
+
+1. **`on_message` hook** — Captures incoming platform messages and broadcasts `channel_message` events with sender name, platform, and icon
+2. **`_session.chat()` wrapper** — Wraps the agent's chat method so responses are also broadcast as `channel_response` events
+3. **Persistence** — All messages saved to the datastore under session `channel-{channel_id}` for history on reload
+
+### Frontend (`chat.js`)
+
+| Function | Purpose |
+|---|---|
+| `_handleChannelMessage(data)` | Renders incoming platform user messages; auto-switches to channel session if on fresh chat |
+| `_handleChannelResponse(data)` | Renders agent responses from channel bots |
+| `_appendChannelMsg(role, data)` | Creates message DOM with platform badge, icon, sender name |
+| `_markSessionUnread(sessionId)` | Adds unread dot to sidebar for inactive channel sessions |
+
+## Performance
+
+Every broadcast is dispatched via `asyncio.create_task()` — the original bot message handling is **never blocked**. Errors in broadcasting are logged at `debug` level and swallowed — the bot continues normally even with zero Chat UI clients connected.
+
+## Session Naming
+
+Each channel gets a dedicated session: `channel-{channel_id}`. Platform icons:
+
+| Platform | Icon |
+|---|---|
+| Slack | 💬 |
+| Discord | 🎮 |
+| Telegram | ✈️ |
+| WhatsApp | 📱 |
+
+## WebSocket Events
