Walkthrough

The flake.nix configuration was updated to upgrade the Go development environment from version 1.23 to 1.25, add support for unstable Nixpkgs packages, and reorganize the package configuration into separated stable, unstable, and other package groups for better modularity.

Changes

Cohort / File(s)	Summary
Version and Dependency Updates flake.nix	Updated flake description and Go version from 1.23 to 1.25; updated nixpkgs.url to 0.2511 and added new nixpkgs-unstable input.
Function Signature and Outputs flake.nix	Expanded outputs function signature to include nixpkgs-unstable parameter; added pkgs-unstable binding for unstable Nixpkgs set; updated function call to pass pkgs-unstable argument.
Package Configuration Reorganization flake.nix	Restructured overlays to remove self.overlays.default; replaced allowUnfree boolean with allowUnfreePredicate function; separated packages into three composable groups—stablePackages (antlr, ginkgo, go\_1\_25, goperf, gotools, just), unstablePackages (golangci-lint), and otherPackages (goreleaser-pro); removed goVersion binding.

🐰 A flake so fine, now version twenty-five,
With unstable packages thriving and alive!
Partitioned sets dance in harmony so sweet,
Go's toolchain updated, the journey's complete! 🚀
