Rust-analyzer stops returning misleading None values when const evaluation fails, aligning more closely with rustc's error handling strategy.

Rust-analyzer landed a critical fix that returns proper error constants to the solver when consteval fails [1], rather than incorrectly reporting None for cases like 32-bit architecture mismatches. The same commit also fixed rustc_private support for rustc_proc_macro [2], addressing integration issues with private compiler APIs. Both fixes rolled into the nightly release [3]. On the ecosystem side, crates.io bumped shiki to v4.4.3 [4] and futures-util to v0.3.34 [5], keeping the JavaScript and Rust dependency stacks current. Meanwhile, the compiler team merged 23 pull requests including stabilization work on allocators [6], f128 support on LLVM 23+, and a critical performance fix for the unic-ucd crate by avoiding fully_perform_locally with the next solver [7]. A PowerPC inline ASM fix corrected scalar float lane positioning on little-endian systems [8]. Across all desks, 89 commits and 26 PRs shipped in the last 24 hours.
