fix(ci): move install to nix action

[ryoppippi]

Summary by cubic

Centralize Nix environment setup in the shared setup-nix action and remove redundant init/install steps from CI, dry-publish, and release. This reduces duplication and streamlines builds.

• Refactors
  • setup-nix: load the Nix dev environment (nix develop --command true).
  • ci.yaml: remove explicit Nix init step.
  • dry-publish.yaml: remove pnpm install; run via nix develop.
  • release.yaml: remove pnpm install; run via nix develop.

Pull request overview

This PR refactors CI/CD workflows by consolidating Nix environment initialization into a reusable setup-nix action. The change leverages the shellHook in flake.nix which automatically installs pnpm dependencies when the Nix development environment is loaded, eliminating the need for explicit pnpm install steps in individual workflows.

Key changes:

• Centralized Nix environment initialization in the setup-nix composite action
• Removed redundant pnpm install --frozen-lockfile steps from workflow files
• Removed duplicate nix develop --command true initialization from CI workflow
