RUST CI BREAKS ON KERNEL.ORG OUTAGE, MIRRORING FIX LANDS

The ARM cross-compilation pipeline went dark when kernel.org became unreachable, but the infrastructure team has already pushed the mirror strategy live.

Rust's CI infrastructure hit a critical wall overnight when armhf-gnu builds started failing due to direct dependencies on kernel.org archives [1]. The outage exposed a fragile supply chain: CI was pulling kernel v4.x artifacts from a single source with no fallback. The fix is already merged [2], mirroring kernel archives into ci-mirrors to break the direct dependency and add resilience. Cargo also got a routine submodule bump [3] with 13 commits including a fix for `Compilation::deps_output` only capturing the last dependency. On the libc front, the team shipped tooling to unblock the release cycle: a changelog generator [4], a backport relabeling utility [5], and a multi-target build checker [6] that lets contributors verify builds across all relevant platforms in one command. rust-analyzer landed diagnostics for invalid union patterns [7], catching the E0784 case when patterns contain multiple fields or the rest operator, and fixed SCIP position tracking to exclude trivia so IDE navigation stays precise [8]. The vanta SDK suite got bumped across all packages [9] [10] [11] [12] [13] without incident.
