feat: add support for --profile and --features flags

Add support for custom build profiles and features in cargo-shuttle run command:
- Add --profile flag to specify custom build profiles (e.g., --profile production)
- Add --features flag to specify cargo features (e.g., --features "feature1 feature2")
- Ensure --profile conflicts with --release to avoid confusion
- Properly combine custom features with existing "shuttle" feature when present

This allows users to have more control over the build process, matching
the flexibility of standard cargo commands.
