Problem:
In the BigData grid example, the "Increase Counter" button modifies a record property in place (record.counter++), but the UI does not update.

Causes:

1. Row Update Failure: In-place record updates maintain the same record reference and rowIndex. The new Neo.grid.Row architecture relies on reactive config changes to trigger updates. Since the values are strictly equal, row.record = record does not trigger afterSetRecord, and thus no VDOM update occurs.
2. Animation Failure: The AnimatedChange column implementation is obsolete. It currently attempts to find the cell node within body.vdom and call body.update(). With the new architecture, the Body VDOM is a container of Row components, not the full cell markup. The column needs to target the specific Row component's VDOM and trigger a row-level update.

Solution:

1. Force Row Update: Update GridBody.onStoreRecordChange to explicitly call row.createVdom() when a record is modified, ensuring the new data is rendered even if the record reference hasn't changed.
2. Refactor Animation: Update src/grid/column/AnimatedChange.mjs to:
   • Locate the correct Row component instance.
   • Modify the Row's VDOM to add the animation class.
   • Call row.update() instead of body.update().
