Issue:
Test: Enhance Unit Test Coverage for CLI, Cuegen, and Docgen Packages
#### Description

To improve the overall quality, stability, and maintainability of the KubeVela codebase, our goal is to increase unit test coverage. Good test coverage is essential for preventing regressions and enabling developers to refactor and add new features with confidence, particularly in core utility and code generation packages.

#### Task Description

This task involves a significant effort to add comprehensive unit tests and refactor existing tests across several core packages, including `references/cli`, `references/cuegen`, and `references/docgen`. Many of these packages had critical coverage gaps, and their existing tests did not consistently follow modern best practices.

#### Affected Packages

*   `references/cli/top/config`
*   `references/cli/top/model`
*   `references/cli/top/utils`
*   `references/cuegen`
*   `references/docgen`

#### Key Contributions

This effort includes several key improvements:

*   **Refactored dozens of existing tests** across all affected packages to use consistent, modern testing patterns like table-driven tests and `t.Run()` for sub-tests.
*   **Added comprehensive unit tests for the `docgen` package**, covering core functions for parsing and generating documentation for CUE, Terraform, and OpenAPI schemas.
*   **Added extensive unit tests for the `cuegen` package**, including the generator, provider, and converter libraries to ensure robust CUE code generation.
*   **Enhanced test coverage for `vela top` CLI functionality**, including theme/color configuration, data models, and utility functions.
*   **Uncovered and fixed bugs during the testing process**, including a race condition in the `i18n` test suite and several logical errors in the functions under test, improving the overall stability of these packages.

#### Benefits

This work significantly:
*   Increases the reliability of the CLI and code generation features by preventing regressions.
*   Improves test maintainability by adopting modern testing patterns across multiple packages.
*   Facilitates future development by providing a robust testing foundation for core KubeVela utilities.

+## What it does
+
+1. **Installs Kind CLI** - Downloads Kind v0.29.0 using Go
+2. **Cleans up** - Removes any existing Kind clusters
+3. **Creates cluster** - Spins up Kubernetes v1.31.9 cluster
+4. **Sets up environment** - Configures KUBECONFIG for kubectl access
+5. **Loads images** - Builds and loads Docker images using `make image-load`

+# KubeVela Webhook Debugging Guide
+
+This guide explains how to debug KubeVela webhook validation locally, particularly for the feature that validates ComponentDefinitions, TraitDefinitions, and PolicyDefinitions to ensure they don't reference non-existent CRDs.
+
+## Overview
+
+The webhook validation feature checks that CUE templates in definitions only reference Kubernetes resources that exist on the cluster. This prevents runtime errors when non-existent CRDs are referenced.
+
+## Prerequisites
+
+- Docker Desktop or similar container runtime
+- k3d for local Kubernetes clusters
+- VS Code with Go extension
+- kubectl configured
+- openssl for certificate generation
+
+## Quick Start
+
+```bash
+# 1. Complete setup (cluster + CRDs + webhook)
+make webhook-debug-setup
+
+# 2. Start VS Code debugger
+# Press F5 and select "Debug Webhook Validation"
+```
+
+## Detailed Setup Steps
+
+### 1. Environment Setup
+
+```bash
+# Create k3d cluster
+make k3d-create
+
+# Install KubeVela CRDs
+make manifests
+kubectl apply -f charts/vela-core/crds/
+```
+
+### 2. Webhook Certificate Setup
+
+The webhook requires TLS certificates with proper Subject Alternative Names (SANs) for IP addresses.
+
+```bash
+# Generate certificates and create Kubernetes secret
+make webhook-setup
+```
+
+This creates:
+- CA certificate and key
+- Server certificate with IP SANs (127.0.0.1, Docker internal IP, local machine IP)
+- Kubernetes Secret `webhook-server-cert` in `vela-system` namespace
+- ValidatingWebhookConfiguration pointing to local debugger
+
+### 3. Start Debugger in VS Code
+
+#### VS Code Launch Configuration
+
+If you're using VSCode add this configuration to `.vscode/launch.json`:
+
+```json
+{
+    "version": "0.2.0",
+    "configurations": [
+        {
+            "name": "Debug Webhook Validation",
+            "type": "go",
+            "request": "launch",
+            "mode": "debug",
+            "program": "${workspaceFolder}/cmd/core",
+            "args": [
+                "--log-debug=true",
+                "--metrics-addr=:8080",
+                "--enable-leader-election=false",
+                "--use-webhook=true",
+                "--webhook-port=9445",
+                "--webhook-cert-dir=${workspaceFolder}/k8s-webhook-server/serving-certs"
+            ],
+            "env": {
+                "KUBECONFIG": "${env:HOME}/.kube/config",
+                "POD_NAMESPACE": "vela-system"
+            },
+            "showLog": false,
+            "console": "integratedTerminal"
+        }
+    ]
+}
+```
+
+#### Set Breakpoints
+
+Recommended breakpoint locations:
+- `pkg/webhook/core.oam.dev/v1beta1/componentdefinition/validating_handler.go` - ComponentDefinition handler
+- `pkg/webhook/core.oam.dev/v1beta1/traitdefinition/validating_handler.go` - TraitDefinition handler
+- `pkg/webhook/core.oam.dev/v1beta1/policydefinition/validating_handler.go` - PolicyDefinition handler
+- `pkg/webhook/core.oam.dev/v1beta1/workflowstepdefinition/workflowstep_validating_handler.go` - WorkflowDefinition handler
+
+#### Launch Debugger
+
+1. Open VS Code
+2. Press `F5` or go to Run → Start Debugging
+3. Select **"Debug Webhook Validation"** configuration
+4. Wait for webhook server to start (look for message about port 9445)
+
+The debugger configuration includes:
+- `--use-webhook=true` - Enables webhook server
+- `--webhook-port=9445` - Port for webhook server
+- `--webhook-cert-dir` - Path to certificates
+- `POD_NAMESPACE=vela-system` - Required for finding the secret
+
+## Make Targets Reference
+
+| Target | Description |
+|--------|-------------|
+| `make webhook-help` | Show webhook debugging help |
+| `make webhook-debug-setup` | Complete setup (cluster + CRDs + webhook) |
+| `make k3d-create` | Create k3d cluster |
+| `make k3d-delete` | Delete k3d cluster |
+| `make webhook-setup` | Setup certificates and webhook configuration |
+| `make webhook-clean` | Clean up webhook environment |
+
+## Troubleshooting
+
+### Connection Refused Error
+
+If you get "connection refused" errors:
+1. Ensure the debugger is running in VS Code
+2. Check that port 9445 is not blocked by firewall
+3. Verify the webhook server started (check VS Code console)
+
+### TLS Certificate Errors
+
+If you get certificate validation errors:
+1. Regenerate certificates: `make webhook-setup`
+2. Restart the debugger
+3. Ensure IP addresses in certificates match your setup
+
+### Webhook Not Triggering
+
+If the webhook doesn't trigger:
+1. Check ValidatingWebhookConfiguration: `kubectl get validatingwebhookconfiguration`
+2. Verify the webhook URL matches your debugger's IP
+3. Check namespace is correct (vela-system)
+
+### Secret Not Found
+
+If you see "Wait webhook secret" messages:
+1. Ensure the secret exists: `kubectl get secret webhook-server-cert -n vela-system`
+2. Recreate if needed: `make webhook-setup`
+
+## How It Works
+
+1. **Certificate Generation**: Creates TLS certificates with proper SANs for local IPs
+2. **Secret Creation**: Stores certificates in Kubernetes secret
+3. **Webhook Configuration**: Creates ValidatingWebhookConfiguration pointing to local debugger
+4. **Debugger Startup**: VS Code starts the webhook server on port 9445
+5. **Validation**: When definitions are applied, Kubernetes calls the webhook
+6. **Debugging**: Breakpoints allow stepping through validation logic
+
+## Files and Components
+
+- **Script**: `hack/debug-webhook-setup.sh` - Main setup script
+- **Makefile**: `makefiles/develop.mk` - Make targets for debugging
+- **VS Code Config**: `.vscode/launch.json` - Debugger configuration
+- **Test Files**: `test/webhook-*.yaml` - Test manifests
+- **Validation Logic**: `pkg/webhook/utils/utils.go` - Core validation implementation
+- **Handlers**: `pkg/webhook/core.oam.dev/v1beta1/*/validating_handler.go` - Resource handlers
+
+## Clean Up
+
+```bash
+# Clean up webhook setup
+make webhook-clean
+
+# Delete k3d cluster
+make k3d-delete
+```
+
+## Tips
+
+1. **Always start the debugger before testing** - The webhook configuration points to your local machine
+2. **Use breakpoints wisely** - Too many breakpoints can cause timeouts
+3. **Check logs** - VS Code Debug Console shows detailed logs
+4. **Test both valid and invalid cases** - Ensures validation works correctly
+5. **Keep certificates updated** - Regenerate if IPs change
