fix(hub-ui): keep grouped actions out of dock memory

[SaKaNa-Y]

Summary

• stop grouped action entries from replacing the last-opened dock panel
• ignore action IDs persisted by older clients when resolving the preferred group child
• add regression coverage for persistence and fallback behavior

Reproduction

In the hub-ui playground, choose Ping in Playground Tools, close the group, then reopen it. Before this change, reopening reruns Ping and the group menu becomes unreachable.

Testing

• pnpm lint
• pnpm knip
• pnpm test (126 files, 1447 passed, 9 skipped)
• pnpm typecheck
• pnpm build
• manual before/after verification in Chrome with the hub-ui playground

Tip

The boxes under View are live. Tick Architecture lens or Data flow lens to choose which diagrams appear, or Expand every detail to open every drill-down at once. The comment redraws in place a few seconds later.

🪧 More tips

• Run PR Lens on your own machine: npx skills add coldteadotai/pr-lens installs the agent skill. Then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
• Draw a diff before it is even a pull request: npx @coldtea/pr-lens-cli analyze --base origin/main reads the diff with your own model key, and npx @coldtea/pr-lens-cli render .pr-lens/graph.json draws the same lenses on your machine.
• Show unchanged neighbours lists the components this change did not touch alongside the ones it did, so the drill-down shows what the changed code sits next to.
• GitHub will not let you zoom an image in a comment. The link under each diagram opens it full size on a page of its own, where you can.
• The CLI's render picks up .github/pr-lens.yml automatically and applies your corrections (renames, exclusions, lane pins) at draw time.
• Would you rather run it from CI on a key of your own? Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and a model key in your repository secrets, say GEMINI_API_KEY. The Action asks Gemini by default, or OpenAI and any endpoint speaking /chat/completions through its provider input.
• PR Lens is free for open source. A star on the repository is what keeps it going.
• Push a new commit and the whole comment re-renders for the new head. An older run never overwrites a newer one, so a slow render cannot put a stale diagram back.
• The diagrams follow your GitHub theme, so dark mode gets the dark render and light mode the light one, and the moving dots show this pull request's data in motion.
