feat(discord): Add bot presence/status updates with token usage tracking
Integrates presence updates directly into the Discord channel integration:
- Added presence config schema (channels.discord.presence):
- enabled: Toggle presence updates
- showTokenUsage: Show cumulative token count
- format: Custom format string with placeholders ({tokens}, {model}, etc.)
- activityType: Playing, Watching, Listening, Competing (NOT Custom - bots can't use it)
- status: online, idle, dnd, invisible
- Created PresenceManager in src/discord/monitor/presence-manager.ts:
- Tracks cumulative token usage per session
- Formats status text with configurable placeholders
- Interfaces with Carbon GatewayPlugin.updatePresence()
- Created presence registry (src/discord/presence-registry.ts):
- Shared registry for presence managers across accounts
- Exported via plugin-sdk for extension access
- Wired up message_sent hook in Discord extension:
- Hook triggers after each reply is delivered
- Updates bot presence with session token counts
Config example:
```json5
channels: {
discord: {
presence: {
enabled: true,
showTokenUsage: true,
format: "📊 {tokens} tokens",
activityType: "Watching", // Shows: "Watching 📊 1,234 tokens"
status: "online"
}
}
}
```
Note: Discord API limitation - bots cannot use Custom activity type (type 4).
Available types: Playing, Watching, Listening, Competing.
