chore(ai): sync LobeHub models at 6c7a6fb033e4

check-rust.yml 的 shear 任务在 Rust 1.95 工具链下装最新
cargo-shear(1.14.0) 失败：其依赖 ra_ap_syntax 0.0.352 要求
rustc >= 1.98。且 binstall 走 GitHub release 下载时遭遇
api.github.com 403，回退源码编译后同样因版本过高而失败。

钉到 cargo-shear@1.13.4（依赖 ra_ap_syntax 0.0.347，要求
rustc 1.95），与 CI 的 stable 工具链兼容。
