Module fastvideo 

FastVideo installer — native Rust build for ROCm gfx11 support.

Clones scooter-lacroix/FastVideo and checks out an audited immutable commit, then builds both Python distributions against Rusty’s managed ROCm environment.

Instead of delegating to ./build.sh --rocm (which calls uv pip install without --system and fails outside a venv), this module replicates the build steps individually with proper env var injection and pip prefix handling consistent with the rest of the rusty-stack installer ecosystem.
