Upstream numtide/llm-agents.nix removed overlays.default and only keeps overlays.shared-nixpkgs.

Root cause: The CI workflow runs nix flake update before the check step, which pulls the latest llm-agents.nix revision. That revision no longer exports overlays.default, causing:

error: attribute 'default' missing
at modules/nixpkgsConfig.nix:70:5

Fix: Use overlays.shared-nixpkgs instead. It does the same thing (provides pkgs.llm-agents.*) but builds packages against the consumer's nixpkgs instead of using pre-built flake packages.

Affected runs: #3125–#3134 (all failing since the upstream change)

Upstream [numtide/llm-agents.nix](https://github.com/numtide/llm-agents.nix) removed `overlays.default` and only keeps `overlays.shared-nixpkgs`. **Root cause:** The CI workflow runs `nix flake update` before the check step, which pulls the latest llm-agents.nix revision. That revision no longer exports `overlays.default`, causing: ``` error: attribute 'default' missing at modules/nixpkgsConfig.nix:70:5 ``` **Fix:** Use `overlays.shared-nixpkgs` instead. It does the same thing (provides `pkgs.llm-agents.*`) but builds packages against the consumer's nixpkgs instead of using pre-built flake packages. **Affected runs:** #3125–#3134 (all failing since the upstream change)
Upstream llm-agents.nix removed overlays.default in favor of
overlays.shared-nixpkgs. The default overlay was using pre-built
packages from the flake, while shared-nixpkgs builds them against
the consumer's nixpkgs — which is the recommended approach anyway.

This fixes all failing CI runs (#3125–#3134) that fail at the
'nix flake archive/check' step with:
  error: attribute 'default' missing
  at modules/nixpkgsConfig.nix:70:5
update flake.lock: llm-agents -> 5c73869 (overlays.shared-nixpkgs)
