Cobb caught the regression on vc=60: subs feed only showed LTT +
WTYP because vc=56's RSS path emitted raw ISO timestamps in
upload_date_relative, but Kotlin's recencyScore() parser only
understands 'N units ago' format. Every item tied at MIN_VALUE,
sort order went to whichever channel resolved first in the
50-concurrent fan-out — LTT + WTYP just happened to win the race.
Fix in feed.rs: parse the RFC3339 published timestamp, compute
delta from now, format as 'N second/minute/hour/day/week/month/year
ago'. Matches recencyScore's regex exactly. RSS still gives ISO;
we convert at the Rust boundary.
Standalone RFC3339 parser (no chrono dep) — Howard Hinnant's
civil-to-days algo, 30 lines, handles negative years correctly.
Display ALSO benefits — UI was showing the raw ISO string
('2026-05-19T13:00:31+00:00') in the channel row. Now reads
'7 days ago' like every other YT client.
