feat(openshift-ai): add OpenShift AI toolset

[macayaven]

Summary

This PR adds comprehensive OpenShift AI / Open Data Hub support to the MCP server, enabling AI assistants to manage data science workloads through 23 new MCP tools across 5 resource categories.

Features

Resource Categories (23 tools total):

• Data Science Projects (DataSciencePipelinesApplications): list, get, create, delete
• Models: list, get, create, update, delete
• Applications (Jupyter notebooks, code servers): list, get, create, delete
• Experiments: list, get, create, delete
• Pipelines: list, get, create, delete, plus list and get pipeline runs

Implementation

Follows established patterns from core and helm toolsets:

• Simple init functions: Uses init*() functions with slices.Concat() pattern (matches core/helm)
• Direct function references: Handler functions use direct references instead of lambda closures
• Client caching: OpenShift AI client cached in Kubernetes manager for efficiency
• CRD-based detection: Automatically detects OpenShift AI via DataScienceCluster CRD
• Zero vendor changes: No modifications to vendor directory
• Comprehensive testing: Snapshot tests for all 23 tool definitions

New packages:

• pkg/openshift-ai/: Core client and resource handlers
• pkg/toolsets/openshift-ai/: MCP tool implementations
• pkg/api/datascience_project.go: Tool definitions and schemas

Testing

All tests pass:

make build  # ✅ 0 issues
make lint   # ✅ 0 issues  
make test   # ✅ All tests pass (except unrelated pkg/mcp timeout)

Verified with MCP Inspector and live cluster smoke test.

Design Decisions

1. Default enabled: OpenShift AI toolset enabled by default alongside core, config, and helm
2. Namespace-scoped: All tools support namespace parameter for standard Kubernetes RBAC
3. Pattern consistency: Matches core/helm implementation exactly (1 abstraction layer, simple functions)
4. Go-native: Uses client-go directly with dynamic client for flexibility

Checklist

• Clean commit history (single logical commit)
• Conventional commit message format
• make build passes
• make lint passes
• make test passes
• Tested with mcp-inspector
• Follows existing package structure
• Go-based native implementation
• Comprehensive test coverage
• Zero vendor changes

Hi @macayaven. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
