fix: do not link a cluster repair target

[SebTardif]

What Problem This Solves

A repair action whose target was cluster:... was rendered as a link to that text. That hid a real pull or issue URL stored on the same action.

Why This Change Was Made

targetLink links action.pr or action.url when either is a GitHub issue or pull URL. A cluster: target is left as plain text.

• scripts/repair-dashboard.mjs
• test/repair-dashboard.test.mjs

User Impact

A blocked cluster repair shows the pull number as a link. A completed close shows the issue number as a link. The cluster: target is not a link.

Evidence

renderRepairDashboard from commit 0c3156e read one run file. The fix action target was cluster:issue-openclaw-openclaw-5 and its pull URL was https://github.com/openclaw/openclaw/pull/9. The apply action target was cluster:issue-openclaw-openclaw-8 and its issue URL was https://github.com/openclaw/openclaw/issues/8.

cluster_links is the count of markdown links whose destination starts with cluster:.

Real behavior proof

• Behavior or issue addressed: A cluster: repair target is not linked. The action's pull or issue URL is linked instead.
• Real environment tested: macOS, Node, renderRepairDashboard from commit 0c3156e, one JSON run file under a temporary results directory.
• Exact steps or command run after this patch: Write a run whose fix action target is cluster:issue-openclaw-openclaw-5 and whose pr is pull 9. Write an apply action whose target is cluster:issue-openclaw-openclaw-8 and whose url is issue 8. Render the dashboard.
• Evidence after fix: The blocked row links [#9](https://github.com/openclaw/openclaw/pull/9). The completed row links [#8](https://github.com/openclaw/openclaw/issues/8). cluster_links is 0.
• Observed result after fix: The cluster target is not a clickable destination. The pull and the issue are.
• What was not tested: A publish to the state branch. The render read a local results directory.
