fix: pass actual chat JID to agent runner instead of group folder

watch_ci tasks in perf channel were silently failing because
NANOCLAW_CHAT_JID was set to the group folder name (e.g. "eyejokerdb-4")
instead of the actual Discord JID. The scheduler rejected the task with
"target group not registered".

Also adds a fallback in ipc.ts to resolve folder names to registered
JIDs when a folder name is passed instead of a JID.
