…QE queries Parse the physicalPlanDescription text to extract 'Initial Plan' and 'Final Plan' sections when AQE rewrites the plan. Display them with a Unified/Split toggle button group: - Unified (default): full plan text as before - Split: two columns showing Initial Plan (left) vs Final Plan (right) For non-AQE queries (where initial == final), the raw text is shown directly without the toggle.

What changes were proposed in this pull request?
Add a side-by-side comparison view for AQE plan evolution on the SQL execution detail page.
When AQE rewrites a query plan, the Plan Details section now shows a Unified | Split toggle:
For non-AQE queries (where initial == final), the raw text is shown directly without the toggle.
Why are the changes needed?
Understanding how AQE rewrites a plan is important for query performance analysis. Currently the plan text mixes both versions in a single block, making it hard to compare. The split view makes differences immediately visible (e.g., added ShuffleQueryStage, AQEShuffleRead coalescing, statistics).
Does this PR introduce any user-facing change?
Yes — Plan Details section on the SQL execution page now shows a Unified/Split toggle when AQE has rewritten the plan.
How was this patch tested?
Compilation verified. Manual testing with AQE-enabled queries.
Was this patch authored or co-authored using generative AI tooling?
Yes, co-authored with GitHub Copilot.
