fix(ci): MSRV 1.85→1.88 + skip BatBadBut-incompatible win tests

Round-2 CI fix after e72963d.

MSRV: 1.85 still failed because darling 0.23 requires 1.88 (and
icu_collections 2.2 requires 1.86). Bump MSRV to 1.88 in workspace
manifest + GH Actions matrix — same reasoning as before, one bump
beats chasing pin-the-tail-on-the-dep.

Windows: classifier_*tests fail with "batch file arguments are
invalid" — Rust 1.77.2+ blocks argv with quote characters from
reaching .bat/.cmd because of CVE-2024-24576 (BatBadBut). Our
fake-claude shim is a .cmd script; --bare and JSON args
trip the guard. Real claude is a native binary, so this is a
test-fake-only constraint. Mark the 3 affected tests
#[cfg_attr(windows, ignore = "...")] with explanatory comment.
