RUST COMPILER CUTS DEAD CODE IN DROP ELABORATION, CLIPPY FIXES DIVISOR SIDE EFFECTS

The compiler got leaner this cycle while Clippy stopped suggesting broken rewrites, and the ecosystem shipped 89 commits across the core repos.

Two solid refinements landed on the compiler side. Drop elaboration now skips creating reset blocks when there's nothing to reset [1], a cleanup that follows earlier work to optimize MIR generation. Meanwhile, Clippy's manual_div_ceil lint stopped suggesting rewrites that accidentally change how many times a side-effectful divisor gets called [2], fixing a correctness bug that could silently break user code. The core repo also merged five PRs including NEON support for ASCII operations [3] and a jobserver cleanup, pushing steady progress through the optimization pipeline. On the ecosystem front, crates.io absorbed dependency updates across Percy, Vite, and Playwright while adding typed MSW handlers via openapi-msw [4], letting mock definitions stay synchronized with backend contracts. Registry activity was routine: five crates published or updated to crates.io-index [5]. Activity totals: 89 commits, 29 PRs across five repos.
