feat: add ZeroClaw AI agent runtime stack

[akurinnoy]

Description of Changes

Add ZeroClaw as a devfile registry sample - an open-source Rust-based AI agent runtime by ZeroClaw Labs.

The stack runs the ZeroClaw daemon in a sidecar container:

• Gateway server on port 42617 - webhooks, websockets, and web dashboard

The official ZeroClaw image is distroless, so we use a wrapper image (quay.io/che-incubator/zeroclaw-image) that adds a shell environment on UBI9-minimal. The wrapper is built from che-incubator/zeroclaw-image.

The editor (VS Code, ttyd, etc.) is chosen separately in the dashboard and injected into the tools container.

Acceptance Criteria

• Contributing guide

Have you read the devfile registry contributing guide and followed its instructions?

• Test automation

Does this repository's tests pass with your changes?

• Documentation

Does any documentation need to be updated with your changes?

• Check Tools Provider

Have you tested the changes with existing tools, i.e. Odo, Che, Console? (See devfile registry contributing guide on how to test changes)

Tests Performed

• Schema validation passed locally (bash tests/validate_devfile_schemas.sh)
• odo init passed locally with odo v3.16.1
• Started a workspace from the ZeroClaw sample on an OpenShift cluster (CRC, both amd64 and arm64)
• Verified the gateway/dashboard is accessible on port 42617
• Ran zeroclaw quickstart, zeroclaw status, and zeroclaw doctor from the terminal
• Confirmed config persists across workspace restarts (PVC at /home/user/.zeroclaw)

How To Test

1. Build a custom devfile registry image with this change
2. Deploy it to a Che/DevSpaces cluster
3. Create a workspace from the ZeroClaw sample
4. Open the gateway endpoint and run zeroclaw quickstart to create your first agent
5. Verify the dashboard works

Notes To Reviewer

• The official ZeroClaw image is distroless (no shell). This sample uses a wrapper image that adds bash and coreutils on UBI9-minimal
• The daemon is started via args: ["daemon", "--host", "0.0.0.0"] to bypass the wrapper's default entrypoint config step (already handled at image build time)
• The endpoint uses cookiesAuthEnabled: true for authentication through the Che gateway
• No starterProjects - the sample is a standalone agent runtime, not a code project

Summary by CodeRabbit

• New Features
  • Added a new ZeroClaw stack for launching the AI agent gateway/runtime.
  • Included a ready-to-use workspace setup with a tools container, a ZeroClaw service container, persistent storage, and a public HTTPS gateway endpoint.
  • Added built-in commands for quick start, status checks, and diagnostics.

📝 Walkthrough

Walkthrough

Adds a new ZeroClaw stack to the devfile registry: a devfile.yaml defining stack metadata, tools and zeroclaw containers, a gateway endpoint, a PVC volume, and quickstart/status/doctor commands, plus a stack.yaml registering the stack with a default 1.0.0 version.
