The MSRV bump got the floor building, and the job then failed on clippy 1.85
demanding `.and_then(seg_pos)` where clippy 1.95 is silent -- the exact mirror
of the failure fixed one commit ago, where 1.97 rejected a bare `2.0` that
1.95 accepts. Two clippy versions are not a stricter gate than one. They are a
different gate, whose contents are the union of two lint sets that can point in
opposite directions, and which no developer can reproduce without installing
every toolchain in the matrix.
So lints run once, on the pinned stable, over the whole workspace including the
GUI crate. The MSRV job proves the floor compiles and passes its tests, which
is the only claim an MSRV makes. Nothing is lost by not linting at 1.85:
clippy::incompatible_msrv runs in the lint job against the declared
rust-version and is the check that actually catches "you used an API newer than
you promised" -- it reads the floor rather than standing on it.
The borrow is dropped anyway, since it is correct under both versions;
rustfmt then pulled the expression onto one line.
Also fixed by this restructure, though it never got the chance to fail: the
MSRV job had been running `cargo fmt --check` too, and rustfmt output drifts
across versions in the same way.
