Subject: rss: provenance + score calibration in items

Item titles gain a rune-capped source-feed suffix so list views (which
only ever show the channel title) display provenance inline. Item bodies
open with feed, model score, and the batch-wide score median; the median
is computed over every scored entry at poll time and stored on the run
row as a nil-safe pointer, so old rows render without it. /api/status
exposes the median too.
