Fixes #4678

💡 Background and solution

setHovered with datums from multiple series (or any hovered list longer than a collection mark's internal datum array) crashed in filterGraphicsByDatum.

In the isCollectionMark branch, the match predicate did:

elDatum && datum.every((d, index) => keys.every(k => d[k] == elDatum[index][k]))

When elDatum[index] was missing, reading elDatum[index][k] threw (Cannot read properties of undefined).

This change short-circuits when elDatum[index] is absent, so unmatched datums are ignored and no exception is thrown. Non-collection matching is unchanged, so point graphics that do match still highlight.

Repro from the issue gist: a line chart plus setHovered([...data, extraUnmatchedDatum]) no longer throws.

Language	Changelog
🇺🇸 English	fix: ignore unmatched datums when matching collection marks in filterGraphicsByDatum, so setHovered with a longer multi-series datum list does not throw
🇨🇳 Chinese	修复：filterGraphicsByDatum 在集合图元匹配时忽略越界/未匹配 datum，避免多系列 setHovered 抛错

Verification

• eslint --quiet on packages/vchart/src/chart/base/base-chart.ts and the new test: clean
• jest __tests__/unit/chart/filter-graphics-by-datum.test.ts --runner=jest-runner --testEnvironment=node: 3 passed
• Package jest-electron runner hung in this Linux environment (CI uses macos-latest); the node runner is enough for this non-render regression.

Manual repro (if needed)

1. Render a line chart (collection mark) as in https://gist.github.com/CrazyBucket/0b6018dd186c1921ba85165c1bbf177b
2. Call vchart.setHovered([...data, { time: '20:00', value: 12 }])
3. Expected: no throw; unmatched extra datum is ignored
4. For a multi-series BP chart, setHovered([systolicDatum, diastolicDatum]) should highlight matched point graphics and skip collection marks whose internal datum array is shorter
