Guild access tokens are short-lived (~15 min); the inbound socket
survives via socket.io reconnect but the token captured at connect
time goes stale, so attachment downloads (and reply posts) start
401ing on long-lived agents. Re-login with the agent's Fabric API key
on a short TTL and use the fresh token for fetch + post.
Verified live: 'fabric: fetched 1 attachment(s)' now succeeds where it
previously logged 'attachment fetch 401'.

Live round-trip test showed openclaw's SSRF guard blocking the
localhost guild file URL passed via MediaUrls. We already download the
bytes with the agent's guild token, so MediaUrls is redundant and
noisy — provide only local MediaPaths/MediaTypes. Verified: plugin
logs 'fetched N attachment(s)' and the SSRF WARN is gone.

Unlike Discord, Fabric has no message-length cap. Single-chunk chunker
(text -> [text]), textChunkLimit=MAX_SAFE_INTEGER, capabilities
blockStreaming=false, replyOptions.disableBlockStreaming=true -> every
agent reply delivered as exactly one Fabric message.

Real channel-turn dispatch (resolveAgentRoute + finalizeInboundContext +
dispatchInboundReplyWithBase), wakeup->drop/dispatch, messaging target
grammar (fabric:<id>) + outbound.sendText, tools use execute/parameters.
Verified live: human msg in Fabric -> wakeup -> openclaw agent runs ->
reply posted back into the Fabric channel as the agent.
