- drift.rs: Replace `sorted.sort_by(|a, b| b.1.cmp(&a.1))` with idiomatic
`sort_by_key(|entry| std::cmp::Reverse(entry.1))` (clippy::use_sort_by_key).
- list.rs: Change `query_issues` and `query_mrs` from `fn` to `pub fn` so the
TUI crate can call them directly instead of duplicating the query logic.
- vector.rs: Reformat multi-line assert! macro to satisfy rustfmt check
(body moved onto separate lines with trailing message string).
