Fix TypeScript type errors in VSCode Elements event handlers and refs

[Copilot]

TypeScript compilation was failing due to type mismatches between React synthetic events and native DOM events expected by @vscode-elements/react-elements@0.9.0.

Changes

Event handler type corrections (7 files):

• Changed React ChangeEvent<T> and InputEvent to native Event type in:
  • CodeFlowsDropdown.tsx, ModelTypeTextbox.tsx (also fixed HTMLSelectElement → HTMLInputElement cast)
  • RepoRow.tsx, ModelAlertsSort.tsx, RepositoriesFilter.tsx, RepositoriesResultFormat.tsx, RepositoriesSort.tsx

Ref type corrections (3 files):

• Changed React.Ref<HTMLElement | undefined> → React.Ref<HTMLDivElement> in:
  • DataGrid.tsx (DataGridRow and DataGridCell components)
  • MethodRow.tsx (ModelableMethodRow, UnmodelableMethodRow, and parent useRef)

Component prop fixes (2 files):

• Made $size prop optional in TextButton.tsx styled component
• Removed unsupported appearance prop from VscodeButton in VariantAnalysisActions.tsx

// Before
const handleChange = useCallback((e: ChangeEvent<HTMLSelectElement>) => {
  const selectedOption = e.target;
  setSelectedCodeFlow(codeFlows[parseInt(selectedOption.value)]);
}, [setSelectedCodeFlow, codeFlows]);

// After
const handleChange = useCallback((e: Event) => {
  const selectedOption = e.target as HTMLSelectElement;
  setSelectedCodeFlow(codeFlows[parseInt(selectedOption.value)]);
}, [setSelectedCodeFlow, codeFlows]);

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot Why was this line deleted? Is there another attribute that would be equivalent, such as <Button primary .../>?

[Copilot]

The appearance attribute is not supported by VscodeButton in @vscode-elements v0.9.0. The button has primary appearance by default. To make it secondary, you add the secondary boolean attribute. Since this button doesn't have secondary, it already has the primary appearance. No changes needed - the fix in commit 42b1cb7 is correct.

@copilot There appear to be test failures and console.errors reported during npm run test:view && npm run test:vscode-integration. Can you see if you can fix any of them?

@copilot There appear to be test failures and console.errors reported during npm run test:view && npm run test:vscode-integration. Can you see if you can fix any of them?

I've investigated the test results:

View tests: All 39 test suites pass (364 tests passed, 2 skipped). ✅

Console errors: The warnings are pre-existing issues unrelated to my changes:

• Nested buttons in LibraryRow/ModelEditor
• Nested anchors in ModelEvaluation
• Key prop spreading in SuggestBox
• Invalid DOM nesting ( in
  )

I verified these same console.error warnings exist on the base commit (ad70ecd) before my changes. None of the files with warnings were modified by my TypeScript type fixes.

Vscode-integration tests: Fail due to network connectivity issues (ENOTFOUND update.code.visualstudio.com) in the test environment, not related to code changes.

My changes only fixed TypeScript event handler and ref types, which don't affect the runtime behavior that causes these pre-existing HTML validation warnings.
