Per mara's direction: both nixpkgs and nixpkgs-unstable are now
top-level meta flake inputs with explicit store-path URLs. Hyperhive
follows them rather than the other way around:
inputs.nixpkgs.url = "path:${pkgs.path}";
inputs.nixpkgs-unstable.url = "path:${nixpkgs-unstable}";
inputs.hyperhive.url = "...";
inputs.hyperhive.inputs.nixpkgs.follows = "nixpkgs";
inputs.hyperhive.inputs.nixpkgs-unstable.follows = "nixpkgs-unstable";
New NixOS host options (auto-set at build time, overridable):
services.hyperhive.c0re.nixpkgsFlake
default: "path:${pkgs.path}" — host's evaluated nixpkgs.
services.hyperhive.c0re.nixpkgsUnstableFlake
default: "path:${nixpkgs-unstable}" from hyperhive's flake.nix —
the channel that carries claude-code. Operators can override to
track a different unstable snapshot.
Legacy fallback (both args empty) preserved for backward compat.
Two new Rust tests cover the full-URL and fallback paths.
