Root cause: config inner cond had )))) (4 closes) but needed ))) (3).
The 4th ) prematurely closed the outer cond config clause, making
(t (cond ...)) a bare function call to T instead of the cond default.
Also fixed chat-render coordinate bug (:y 1 :x y -> :y y :x 1)
Added backtrace diag (handler-bind all errors, sb-debug to stderr)
Added asdf central-registry push + :force t for stale-cache prevention
