v0.13.24 — MapStats: split bytes_pending into nontried / retryable

bytes_pending was an opaque aggregate of NonTried + NonTrimmed +
NonScraped. UIs that wanted a "will retry in Pass 2-N" bucket were
stuck showing the entire unread disc as Maybe at pct=0.

Adds two granular fields to MapStats:

  bytes_nontried   — Pass 1 hasn't read these yet
  bytes_retryable  — NonTrimmed + NonScraped, Pass 2-N will retry

bytes_pending stays for back-compat (= bytes_nontried + bytes_retryable).

Also picks up the cargo fmt --check lint that's been red on main CI
since v0.13.18 (rustfmt fold differences on a few long format-string
layouts; functional no-op).
