chore(llm-pi-ai): bump pi-ai to 0.81.1 for the gpt-5.6 model catalog

pi-ai 0.80 restructured its entrypoints: the static catalog reads now
live on /providers/all as getBuiltinModels/getBuiltinProviders (keyed by
the catalog-only BuiltinProvider type, replacing KnownProvider at those
call sites), and the global streamSimple moved to /compat. The config
schema gains the new 'max' reasoning level.
