Adds art.mode "host" (now the default): emit each cover's local file PATH
and let the host serve the bytes via its art proxy, instead of inlining a
data URL. The reconcile payload carries no image data, so a large Playnite
library no longer exceeds the host's request-body limit. "dataurl" (inline,
small libraries) and "off" remain. Requires a host with the provider-art
proxy (punktfunk main: feat/library-local-art).
