refactor: simplify Deno support to match other package managers

- deno now follows the same pattern as npm/yarn/pnpm/bun
- unified install step handles all package managers
- support npm dependencies in hybrid Deno projects via deno install
- use package-manager input for Deno version (e.g., [email protected])
