Infuse and SenPlayer build Continue Watching rows from the listing's
MediaSources and discard responses that carry only the detail-field stub,
leaving the row empty. Keep the progress scan list-level (the per-entry
GetItemDetail fanout removed in the error-report-2026-05-08 §6 fix stays
removed), but re-map the returned page — bounded by the request limit,
capped at 100 — through the detail path when the client requests
detail-level Fields, matching HandleLatest's existing pattern. The stub
remains as the fallback past the cap and is made honest: playability
flags set, collections serialized empty instead of null.
