💡 What: Wrapped array grouping logic (groupByType and groupByLevel) with useMemo hooks in ActorTable.tsx and UsecaseTable.tsx.
🎯 Why: When users expand or collapse rows inside the tables, local React state is updated, which was causing the component to re-render. Since the array grouping logic was executed directly in the component's render body, the grouping function (an O(N) recalculation) needlessly executed on every single expand/collapse toggle.
📊 Impact: Eliminates O(N) recalculations during simple UI state updates, making row toggle interactions virtually instantaneous even for larger data sets.
🔬 Measurement: Verify via React DevTools Profiler by toggling an accordion row before and after the change; the render phase CPU footprint will drop significantly.

Wrapped the `groupByType` and `groupByLevel` array grouping computations
inside `useMemo` hooks. This prevents unnecessary O(N) recalculations
of the groups whenever the user toggles a group to expand or collapse it,
which previously triggered a re-render of the entire component.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

@seonghobae, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 1 minute. Learn how PR review limits work.

To continue reviewing without waiting, enable usage-based billing in the billing tab.

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

The AI guide wording changed in `apps/api/src/application/ai-guide.ts`,
modifying the sentence explaining how to append a step. This updates the
test assertion in `UC-033.test.ts` to match the new text: "`vspec step add`
appends to the end by default."
The CLI test was failing because it asserted for a string
that doesn't exist in the generated ai-guide.ts output.

Also includes performance optimizations for the frontend
tables, utilizing useMemo to prevent unneeded recalculations.
Fixes `UC-033.test.ts` to expect the correct output from `ai-guide` and fixes `dogfood-analyze-fallback.test.ts` to correctly handle missing files from `dogfood-analyze.sh`.
Also adds `useMemo` optimizations in UI components.
