fix(ci): resolve nix-update workflow issues

- Remove --use-update-script flag that breaks with flake-only repos
  (nix-update-script expects default.nix at repo root)
- Fix GitHub API jq filter for detecting prereleases
- Fix Summary step bash syntax for handling input variables
- Format lib/ files that were failing formatting check
