OPENCODE_VERSION is read into version and then used to build download URLs (via v${version}), but earlier in this script the guard mistakenly checks releaseId a second time instead of validating version. If OPENCODE_VERSION is unset, this will silently generate vundefined URLs for all targets (including the new Windows arm64 entry). Update the env var validation to throw when version is missing.

In getCurrentSidecar, the thrown error interpolates RUST_TARGET instead of the target argument. This can produce misleading messages (e.g., when target is passed explicitly or when the env var is unset). Use the target parameter in the error message (and the initial guard) so the failure accurately reports which Rust target was requested.
