Dylan M. Taylor caea05eff8 Use jiff for UTC/calendar conversion instead of hand-rolled copies ...

This repo already uses jiff (ui-egui, for the system time zone), so the
hand-rolled Howard Hinnant civil/days-from-civil copies move to jiff rather than
pulling in a second time crate. jiff is lifted to a workspace dependency:
- crates/core/src/time.rs: parse_rfc3339's days_from_civil and civil_from_unix
- xtask/src/local.rs: rfc3339 (feed timestamps)
ui-egui now takes jiff from the workspace. core keeps only civil-date math (no
time zone), so the wasm build is unaffected. Output and parsing semantics are
unchanged and pinned by the existing tests (RFC 3339 parsing, leap days, day
rollover, the feed's YYYY-MM-DDTHH:MM:SSZ). AGENTS.md now says time goes through
jiff.
