Chris Lu dd75add62f filer: fetch only the part of a chunk the view covers
Replaces the PinRandomMode size heuristic with a per-chunk coverage rule.
ViewFromVisibleIntervals already clips chunk views to the request window,
so a view that is not IsFullChunk() is one the request only partially
needs; fetch it as a range regardless of the detected read pattern.

This closes the holes a request-size pin left open: ranges larger than
SeqTolerance no longer revert to whole-chunk downloads once their buffers
look sequential, and ranges that fully cover a chunk keep the shared
whole-chunk path instead of fetching 256KiB slices piecemeal. Prefetch
(MaybeCache) skips clipped views so it cannot amplify a range read either.

PinRandomMode is dropped: no caller needs it once coverage drives the
fetch choice. Range fetches route through fetchChunkDataFn so tests
observe them the same way as whole-chunk downloads.
