Subject: [PATCH 1/2] feat: add nix flake input auto-merge rules to org preset

Add packageRules for the Renovate nix manager (git-refs datasource):
- JacobPEvans-owned inputs: immediate auto-merge
- Trusted Nix ecosystem (NixOS, nix-community, cachix, anthropics,
  etc.): auto-merge after 3-day stabilization

This enables per-repo opt-in via `"nix": { "enabled": true }` in
renovate.json, replacing custom deps-update-flake.yml workflows
with Renovate's native per-input PRs, descriptions, and auto-merge.

Subject: [PATCH 2/2] fix(renovate): add matchDatasources and remove
 ineffective minimumReleaseAge for nix rules

git-refs datasource has no timestamp support, so minimumReleaseAge silently
does nothing. Add matchDatasources: ["git-refs"] to scope nix rules precisely.
Update trusted rule description to reflect immediate merging.
