Add exclusion paths for the workspace, Cargo home, and Rustup home to disable Windows Defender real-time scanning during Rust compilation. This is a well-known optimization that can reduce Windows build times by 20-40%. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
✅ Deploy Preview for rolldown-rs canceled.

The env vars may not be set on GitHub runners, causing null argument errors. Fall back to ~/.cargo and ~/.rustup defaults. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add setup-dev-drive action to create an NTFS Dev Drive for the workspace, CARGO_HOME, and RUSTUP_HOME. Dev Drives bypass Windows Defender minifilter and provide faster I/O for developer workloads. This also ensures CARGO_HOME/RUSTUP_HOME env vars are set for the Defender exclusion step. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

ReFS enables native Dev Drive support which automatically bypasses the Windows Defender minifilter. Remove workspace-copy since source files stay in the original workspace — only CARGO_HOME and RUSTUP_HOME benefit from the faster drive. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Pull request overview
Updates the Windows CI execution environment in reusable Rust workflows to speed up compilation-heavy I/O by creating a Dev Drive and relocating Rust/Cargo home directories onto it.
Changes:
- Add
samypr100/setup-dev-driveto Windows runs in the reusable native build workflow. - Add
samypr100/setup-dev-driveto Windows runs in the reusable cargo test workflow. - Map
CARGO_HOMEandRUSTUP_HOMEto paths on the Dev Drive to reduce Defender overhead and improve filesystem performance.
