fix: nix develop flake output

[DinoLeung]

Summary

• Fix the flake output layout so nix develop finds devShells.default instead of falling back to the package derivation.
• Move apps.default to the proper top-level per-system flake output.
• Share native/build inputs between the package derivation and dev shell.
• Add LIBCLANG_PATH for bindgen/libclang-backed dependencies.
• Add cargoLock.outputHashes for the patched librespot git dependencies so nix build can vendor them reproducibly.

Testing

• nix flake show --all-systems
• nix develop --command true
• nix develop --command cargo --version
  • Output included: cargo 1.93.0
• nix develop --command pkg-config --modversion openssl
  • Output: 3.6.1
• nix develop --command printenv LIBCLANG_PATH
  • Output pointed to the Nix libclang store path.
• nix-prefetch-git for LargeModGames/spotatui-librespot
  • Confirmed hash: sha256-F1pAhVgxYsbmLXOcbOEU6mGYZO1n94EWCXn5yjhPxv0=
• nix build --no-link
  • Confirmed the previous Cargo vendoring/hash failure is fixed.
  • Build reached the final spotatui derivation; full package build did not complete during the validation window.

Additional notes

• The seven librespot-* output hash entries use the same hash because they all come from the same pinned git repo/revision.

Summary by CodeRabbit

• Chores
  • Centralized Rust build dependencies in the build configuration for consistent behavior across builds and development shells.
  • Added/updated output hash mappings for bundled librespot crate versions to strengthen dependency integrity.
  • Refreshed the development environment setup, including native tooling and LIBCLANG_PATH, to improve local build reliability.
  • Reformatted the packaged application output definition for clearer attribute structure.

📝 Walkthrough

Walkthrough

The flake centralizes Rust build inputs, pins output hashes for librespot crates, reuses those inputs in the package and development shell, and configures LIBCLANG_PATH. The default app attribute formatting is also updated.

Changes
