Pairing-code delivery was hardwired to Discord DM (notifyBotToken +
adminUserId required). Make the provider config-selectable.
- core/config.ts: add notifyProvider ("discord"|"fabric", default
"discord" for back-compat); discord fields required only for discord;
add fabric block (centerApiBase/apiKey/guildNodeId/channelId) required
only for fabric
- notifications/types.ts: neutral PairingNotificationService interface
(DiscordNotificationService kept as back-compat alias)
- notifications/fabric.ts: post the pairing message to a Fabric channel
(agent/login -> guild token -> POST messages); self-contained, no
Fabric plugin dependency
- notifications/factory.ts: select provider from config
- core/runtime.ts: wire via factory
- openclaw.plugin.json: notifyProvider enum + fabric object; drop
notifyBotToken/adminUserId from required (conditional in code)
- tests: fabric notifier + provider-selection config (80 passing)
