fix(plugin): force automatic source-reply delivery (fixes no-reply)

OpenClaw defaults group-chat replies to sourceReplyDeliveryMode
'message_tool_only', which suppresses auto-delivery of the agent's
text reply (it expects the agent to call a message tool). With
ChatType 'group', the Fabric plugin's deliver callback was therefore
NEVER invoked — the agent ran but no reply ever returned to Fabric.

Fabric already gates *when* an agent speaks via the per-recipient
wakeup flag, so once a turn is dispatched the reply must always flow
back. Pass replyOptions.sourceReplyDeliveryMode='automatic' so
OpenClaw delivers the agent's reply through  regardless of
the group default (source-reply-delivery-mode honors a truthy
requested mode).

Verified live end-to-end: human posts -> wakeup -> agent runs ->
'fabric: deliver' + 'fabric: posted reply' -> agent message appears
in the Fabric channel.
