fix patch pass: exclude Unreadable from work list; expose bytes_bad_in_title; clippy 1.86 fixes

- patch(): only process NonTrimmed + NonScraped ranges (Unreadable=terminal, NonTried=not-yet-swept)
- bytes_bad_in_title: pub fn for autorip main-movie lost_ms computation
- Clippy 1.86: saturating_sub, unused assignments, unused variable
- fmt: rustfmt formatting
