feat: integrate crane library and enhance Rust build configuration

[arunabha003]

This PR integrates the Crane library into Bria’s Nix setup and strengthens the Rust build/check pipeline around reproducible package builds and repository-level checks.

Implemented in this PR:

• added Crane as a flake input
• expanded flake.nix to build Rust dependencies separately and then build the package via Crane
• introduced package/check outputs for the Rust project in Nix
• wired in repo-level checks such as formatting, clippy, and audit within the Nix build flow
• updated Makefile and build.rs-related configuration to fit the new build path

I'm unable to build the binary, logs below:

should this not be using nix now ?

@arunabha003 I think I found the reason for the error above. I am running nix in a sandboxed mode, and network access is disabled during the build phase. Maybe sandboxed mode is set to false on your system. Can you share the output of nix-info -m?

[arunabha003]

Arunabhas-MacBook-Air:bria arunabha003$ nix run nixpkgs#nix-info -- -m
 - system: `"aarch64-darwin"`
 - host os: `Darwin 24.5.0, macOS 15.5`
 - multi-user?: `yes`
 - sandbox: `no`
 - version: `nix-env (Determinate Nix 3.5.2) 2.28.3`
 - nixpkgs: `/nix/store/9g7vwfbsk7hcp12vrm8a82cnv6y9v8fb-source`
 

Yes the Sandbox mode appears to be set false in my system...Should I try to make it true?

[krtk6160]

I think we can remove these three targets
