Clean up template configurations for initialized projects

Removed unnecessary packages and template metadata from initialized projects:
- Removed TypeScript from vanilla template (not used)
- Removed template.nix from both templates (only needed in repo, not projects)
- Updated flake.nix in templates to only import devshell.nix

Templates now provide minimal, focused development environments.
