Feeds take their channel's first <itunes:category> into a new feeds.category
column; the migration drops ETag and Last-Modified once so every feed re-reads
on its normal schedule and picks one up. /api/popular and /api/directory carry
category and podcast (any audio or video enclosure). Directory becomes a grid of
cover-art tiles under a chip rail: All, Podcasts, Blogs, and a podcast's
categories once Podcasts is picked. Popular and Add a feed keep their rows.
Closes#4, closes#5, closes#6, closes#7.

Conditional GET plus an RSS-first, Atom-fallback parser normalising both
into one entry model, with iTunes explicit and ttl handling carried over
from the Python. Enclosures are recorded as pending; nothing downloads yet.
GUID falls back guid -> link -> enclosure url -> title rather than hashing
the description as the original did.
