"""Per-platform streaming defaults + dashboard exposure.

Streaming is smooth on Telegram (native sendMessageDraft) but flickers on
edit-only platforms like Discord. The shipped defaults encode that:
display.platforms.telegram.streaming=true, .discord.streaming=false. These are
gap-fillers (user values win via deep-merge) and, because the dashboard schema
is generated from DEFAULT_CONFIG, they automatically appear as editable toggles
in the web UI.
