Enhance README to clarify GCP Bucket and staging workspace generation rules

Updated the README to provide clearer descriptions for the `gcp-bucket-crossplane-health` and `stg-workspace-smoke` code bundles. The `gcp-bucket-crossplane-health` now specifies its focus on Kubernetes platform and k8s-kubectl-cmd runtime, while the `stg-workspace-smoke` is noted for its integration of runwhen and tool-builder runtime. This improves documentation clarity for users regarding the purpose and structure of these bundles.

+        # Staging Workspace Smoke Check
+
+        Verify tool-builder runtime can execute a simple custom task against the stg-test workspace.
+
+        **Bundle:** `stg-workspace-smoke` · **Task title:** `Run staging workspace smoke check` ·
+        **Runtime:** tool-builder (python)
+
+        ## When this SLX gets created
+
+        - **Platform:** `runwhen` — workspace-builder matches RunWhen platform resources
+        - **Resource types:** `workspace`
+        - **Match rules (plain English):**
+        - matches every resource (pattern `.+` on name)
+        - **Expected cardinality:** one SLX per matched resource, named `<qualifiers>-stg-smoke`
+        - **Qualifiers:** `workspace`
+
+        ## What this SLX does
+
+        The task runs a python script via the shared `tool-builder` codebundle in
+        `rw-generic-codecollection`. The workspace-builder renders the TaskSet template with
+        a base64-encoded `GEN_CMD` at deploy time; this file shows the decoded script for review.
+
+        ### Script (decoded)
+
+        ```python
+        import os
+
+
+def main():
+    workspace = os.environ.get("WORKSPACE_NAME", "unknown")
+    location = os.environ.get("LOCATION_NAME", "unknown")
+    return [
+        {
+            "issue title": "Staging smoke check passed",
+            "issue description": (
+                f"Tool-builder smoke script ran on workspace={workspace} "
+                f"location={location}."
+            ),
+            "issue severity": 4,
+            "issue next steps": (
+                "No action required — this is an informational smoke test."
+            ),
+        }
+    ]

+
+        ## Deploying this codecollection
+
+        Add to your runwhen-local runner `workspaceInfo.yaml`:
+
+        ```yaml
+        codeCollections:
+          - repoURL: https://<host>/<org>/<your-private-codecollection>.git
+            ref: main
+        ```
+
+        Then reconcile (Flux example):
+
+        ```bash
+        flux reconcile hr runwhen-local -n <runner-namespace> --with-source
+        ```
+
+        > **Requires runwhen-local with `platform: runwhen` support** (RW-1355). Until that
+        > release lands, generation rules using `platform: runwhen` will not render SLXs.
