Description: Gate bytemuck's SIMD impls on rust version, not date, to fix FTBFS
 bytemuck 1.25.0 (vendored by Chromium) ships two implementations of Zeroable/Pod
 for core::simd::Simd, selected with rustversion: one uses core::simd::LaneCount /
 SupportedLaneCount, the other omits them (rust removed those on 2026-01-27;
 upstream bytemuck issue 343). Upstream selects by compiler date.
 .
 rustversion mis-dates Debian's stable rustc 1.95 as before that date, so it picks
 the LaneCount implementation -- but 1.95 already removed LaneCount, and the build
 fails with E0425/E0405.
 .
 Select by rust version instead: before 1.95 (e.g. trixie/bookworm's 1.85) keeps
 the LaneCount implementation; 1.95+ (sid) uses the other. Builds on both.
 .
 Supersedes the earlier bytemuck.patch (it added a bound that 1.25.0 now ships).
