- lib/nntp/xover_client: a minimal one-connection client for seed:range
with XFEATURE COMPRESS GZIP (a zlib stream after "224 … [COMPRESS=GZIP]",
then a "." line; 420 for an empty range). About 6x less header traffic.
Overviews come out with the field names nntp-js uses.
- SfvService.claimAll: one sfv_entries lookup per stored batch.
- Fragments go through the regular ingest path beside fetching (at most
two batches in flight); a failure fails the run at the end.

A seeding node fetches a range over one NNTP connection, parses headers
with the live rules, groups them into files in memory (lib/aggregate) and
stores per complete file its release, the file and a completed binary
(SeedService), instead of one parts row per article. What doesn't complete
within the window goes through the regular ingest path as fragments.
`--dry-run` only fetches and aggregates, to measure a node.
