chore(deps): react 19, react-window 2, globals 17

[alex-clickhouse]

Combines four dependabot bumps into one PR, because three of them cannot pass CI on their own. Replaces #64, #62, #61 and #59.

Package	From	To
react, @types/react	18	19
react-dom, @types/react-dom	18	19
react-window	1.8	2.3
globals	15	17
@types/react-window	1.8	removed

Why they had to be combined

#64 and #62 (React 19) each failed at npm ci with ERESOLVE. Dependabot split the upgrade in two, but @types/react and @types/react-dom peer-require the same major version, so bumping one half leaves the other unsatisfiable. Neither PR was fixable alone.

#61 (react-window 2) got past install and failed the build. Version 2 is a rewrite that removed FixedSizeList, so a version bump alone cannot work.

Required code changes

react-window 2 API migration in src/components/HexViewer/HexViewer.tsx, the only place the library is used:

v1	v2
FixedSizeList	List
children={HexRow}	rowComponent={HexRow}
itemCount / itemSize	rowCount / rowHeight
itemData	rowProps (spread onto the row)
height / width	removed, the list sizes to its container
ref: FixedSizeList	listRef via useListRef
scrollToItem(i, 'center')	scrollToRow({ index: i, align: 'center' })

HexRow now takes RowComponentProps<HexRowData> and reads bytes/highlightMap/onByteClick as direct props instead of a data object.

Because v2 sizes itself to its parent, .hex-viewer becomes a flex column that owns the height and no longer scrolls itself. This drops the height={window.innerHeight - 150} approximation, so the hex view now tracks panel resizes exactly.

@types/react-window@2 is a deprecated stub, so the devDependency is dropped instead of bumped.

React 19 types no longer accept a zero-argument useRef<T>(). saveTimerRef in src/components/QueryInput.tsx passes an explicit undefined.

Verification

All green locally:

• npm run build (eslint + tsc + vite): clean, no warnings
• ELECTRON=true npx vite build: passes
• npm test: 1040 tests in 10 files pass
• npx playwright test: 3 Electron e2e tests pass

The e2e suite does not load data into the hex viewer, so the migration was checked with a throwaway Playwright spec that uploads fixtures/protocol/06-logs.chproto into the Electron app:

• 32 hex rows render
• the list fills its panel exactly (621.8px of 621.8px) with a single scroll container, confirming the flex change
• double-clicking a deep AST node scrolls the hex view (scrollTop 0 to 6022), confirming scrollToRow
• byte highlighting still lines up: the highlighted 05 at 0x12D2 matches the selected packet_type: 5 (EndOfStream) node at [4819:4820]

react-resizable-panels and zustand already declared react ^19 in their peer ranges, so nothing else needed changing.
