Record streams into hidden .live/ and publish finished files via the sweep; plugin 0.1.2 feed wording

Jellyfin indexed in-progress fragmented recordings (no duration -> seek jumped to next episode).
MediaMTX now writes under <Title>/.live/; the sweep remuxes finished files into the title folder
and removes the source. Feed says 'New recording' since it fires after publish.
