🟡 Changes recommended

The PR includes inconsistent verification evidence (.ai/VALIDATION.json reports failing tests while docs/development/STATUS.md claims passing), so the validation record/docs need to be reconciled before approval.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR completes a repository-wide rename from the prior gpu-dialect* crate identity to gust*, updating workspace packages, imports/attributes (#[gust::gpu]), docs, examples, fixtures, and xtask verification routing so the public API and project documentation consistently reflect “GUST”.

Changes:

• Renamed workspace crates and all internal/external references from gpu-dialect, gpu-dialect-macros, gpu-dialect-wgpu to gust, gust-macros, gust-wgpu.
• Updated xtask verification/check-feature commands and added routing tests for check-changed selection logic.
• Refreshed documentation, examples, and golden fixtures/comments to reflect the new naming.
