Serena now adds first-class CUE language support by introducing a dedicated `CueLanguageServer` wired to the official `cue lsp`, enabling CUE-aware LSP behavior (startup + symbol/reference handling) for `.cue` projects.
Scattered source updates, isolated context, and manual follow-up across multiple feeds.
Added a concrete CUE LSP integration path in Serena: new `Language.CUE` registration in the LSP factory and test suite, plus automatic retrieval of the cue binary from cue-lang GitHub releases with SHA-256 verification and per-platform support, while allowing explicit override of binary path or pinned cue version through settings.
Developers editing `.cue` files in Serena can now get CUE language features such as symbol navigation and cross-file references to work immediately when opening CUE repositories, instead of manually wiring or debugging LSP setup themselves. The change uses a pinned default `cue` binary (`v0.16.1`) and verifies downloads by SHA-256 across Linux/macOS/Windows (x64 and arm64), with settings to override both path and version when teams need a custom toolchain. Operators and maintainers should watch for reliability in first-run downloads and for upstream `cue lsp` protocol changes, since either could break startup or reduce LSP completeness for CUE users.
