key differences between api_nu_plugin_kcl and nu_plugin_kcl:

  api_nu_plugin_kcl vs nu_plugin_kcl

  api_nu_plugin_kcl (API-based approach):

  - Uses KCL Rust API directly via kcl-lang crate
  - Commands: kcl-exec, kcl-run (inline code execution)
  - Dependencies: kcl-lang = { git = "https://github.com/kcl-lang/lib" }
  - Functionality: Direct API integration with KCL library
  - Advanced features: Dependency resolution from kcl.mod, external packages support
  - File execution: Can execute multiple KCL files with project management
  - Status: Not tracked in plugin registry (likely experimental/development)

  nu_plugin_kcl (CLI wrapper approach):

  - Uses KCL CLI wrapper via system command execution
  - Commands: kcl-run, kcl-format, kcl-validate
  - Dependencies: Only nushell plugin dependencies (no direct KCL API)
  - Functionality: Wraps KCL CLI commands through subprocess execution
  - Mature features: Full CLI integration with formatting and validation
  - File operations: Single file execution with comprehensive CLI options
  - Status: Tracked in plugin registry, has upstream repository

  Key Architectural Differences:

  1. Integration Method:
    - api_nu_plugin_kcl: Direct Rust API integration
    - nu_plugin_kcl: CLI subprocess wrapper
  2. Capabilities:
    - api_nu_plugin_kcl: Project-aware, dependency management, inline code execution
    - nu_plugin_kcl: Complete CLI feature set (run/format/validate)
  3. Dependencies:
    - api_nu_plugin_kcl: Requires KCL Rust library compilation
    - nu_plugin_kcl: Requires KCL CLI installed on system
  4. Maturity:
    - api_nu_plugin_kcl: Experimental, more complex but potentially more powerful
    - nu_plugin_kcl: Production-ready with comprehensive documentation

  The @ prefix likely indicates that api_nu_plugin_kcl is a variant or experimental version focusing on direct API integration rather
  than CLI wrapping.
