            Weekly automated build from upstream `helix-editor/helix` master.

            - **Upstream Commit**: [${{ steps.sync.outputs.upstream_sha }}](https://github.com/helix-editor/helix/commit/${{ steps.sync.outputs.upstream_sha }})
            - **Fork Commit (with mimalloc patch)**: [${{ steps.sync.outputs.sha }}](https://github.com/${{ github.repository }}/commit/${{ steps.sync.outputs.sha }})
            - **Release Tag**: `${{ steps.version.outputs.tag }}`

            ### 🚀 Performance & ABI Specifications
            - **Allocator**: **`mimalloc`** embedded static allocator.
            - **Instruction Target**: **`x86-64-v3`** (AVX2, FMA, BMI1/2) enabled for **both** core binary and 200+ Tree-sitter parsers.
            - **Compiler Toolchain**: Clang + **Fat LTO** (`opt` profile, single codegen-unit) linked with **`mold`**.
            - **Base Environment**: Ubuntu 22.04 LTS (Glibc 2.35 compatible).
