feat: Add production flag to prune command
This commit introduces a `--production` flag to the `prune` command, allowing users to exclude devDependencies from the pruned output. This is useful for reducing the size of the output when only production dependencies are needed.
The changes include:
- Adding the `production` flag to the `prune` command arguments.
- Modifying the `Prune::new` constructor to accept the `production` flag.
- Updating the `PackageGraph::transitive_closure` to support filtering by dependency type.
- Adding a new `transitive_closure_production` method to `PackageGraph` for production-only closure.
- Updating `Dependencies::new` to correctly parse and store dependency types.
- Adding a test case for `transitive_closure_production`.
