Fix two clippy lints new in Rust 1.95

CI installs the stable toolchain, and Rust 1.95's clippy fails
'cargo clippy --workspace --all-targets -- -D warnings' on main:

- xls/mod.rs: collapsible_match. The XF record's size check becomes a
  match guard; a full table still ignores the record (the catch-all arm).
- passthrough_tests.rs: nonminimal_bool. !is_some_and(x) is written as
  is_none_or(!x).

No change in behaviour.
