Subject: [PATCH] docs(flake): update description and build instructions for
 singularity-forge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Rebrand description: gsd-2 → singularity-forge
- Add RUST_BACKTRACE=1 for better error diagnostics
- Update shellHook message with current build command
- Document native addon build via bun filter

Rust toolchain already present in devShell (cargo, rustc, clippy, rust-analyzer, rustfmt).
