progress: PassProgress carries the located drilldown (emit side)

Add LocatedRange + LocatedProgress to the progress contract and a 'located'
field on PassProgress, populated by the sweep + patch emitters from the
in-memory bad-range set + title. Move the range->chapter/time annotation
(locate_ranges, range_chapter, byte_offset_in_title) into the library so a
client renders the disc map + at-risk movie time straight from PassProgress
and never reads the mapfile itself — if the mapfile becomes a mapdb, this type
and its producer change, clients don't.

PassProgress is no longer Copy (located carries a Vec); it's built once per
throttled emission and passed by reference. Non-locating phases (verify,
extract) emit LocatedProgress::default(). Adds consts::MILLIS_PER_SEC.
Consumer-side wiring (autorip drops Mapfile::load) follows.
