Replace soup's ryoppippi claude-code overlay with the #claude-code package from github:numtide/llm-agents.nix, exposed via a pkgs overlay so sodium.nix's pkgs.claude-code keeps working. Deliberately no nixpkgs.follows: keeps llm-agents' own pin so its binary cache (cache.numtide.com, added to nixConfig) applies, and avoids rebuilding its eagerly-filtered package set against our pin (a sibling pkg wants electron_44 we lack, which otherwise aborts evaluation). On soup's side, mark the claude-code-overlay as deprecated with a TODO to remove it in favor of per-profile llm-agents usage. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
