voyager 3: the window in the Rust edge

The indexer finishes files and releases by posting time instead of the
range path: the frontier is the median Date of the last 1,024 plausible
dates (within 7 days of it; a run of 1,024 agreeing dates moves it), and
a release is finished, judged and written once the frontier is 24 h past
its last part, flagged edge when posted within a day of the block's start.
At the block's end the rest is written provisionally as edges for the
block merger. Files short of parts stay in their release (partial: the
store writes complete = false). Gone: fragments and the cut-off,
uploads_of (online now), check.ts and the fixture comparison; CI replays
the fixtures through edge-bench instead. The wire carries finished, edge
and partial.
