Write match rows per run, categorize interests, and add the interests CLI (steps 4 and 8)

The signals stage upserts each eligible article's matched interests; an
LLM batch files uncategorized interests before the prompt is built (and on
demand as the interests-categorize job); `interests import` and
`interests backfill` load the OPML and seed match rows once.
