feat: in-place row edits for Arrow tables and GeoJSON layers

[igorDykhta]

Summary

• addToDataset / removeFromDataset now mutate Arrow tables with primitive columns in place (concat append, keyed upsert, slice remove). DuckDB still warns and no-ops until INSERT exists.
• GeoJSON layers rebuild dataToFeature when the table revision or row count changes, so appended features show on the map. Filter-only updates still skip a re-parse.
• Live-data example: Arrow and GeoJSON remount a matching table; GeoJSON fetches buildings-australia.geojson at runtime.

Test plan

• yarn test vis-state + data-container + DuckDB no-op
• yarn start:live-data → Arrow: Add / Remove last / Insert then Move tracker (row count stays put)
• GeoJSON: seed buildings appear; Add 1 / Add 5 draw new footprints; Move tracker swaps track-01 without growing the table

Pull request overview

This PR extends Kepler’s in-place row editing flow (addToDataset / removeFromDataset) to work with Arrow-backed datasets (for supported “primitive” Arrow column types), while keeping DuckDB tables as a warned no-op. It also adjusts GeoJSON layer metadata rebuilding so feature parsing stays correct when datasets change via row edits.

Changes:

• Add append / replace / remove support to ArrowDataContainer, with explicit rejection for nested/binary/geoarrow columns.
• Keep DuckDB row edits as a warned no-op at the table layer, and update action/reducer/docs text to reflect Arrow support.
• Rebuild GeoJSON dataToFeature when row count or table revision changes (not on filter-only updates), plus expand tests and the live-data example to cover Arrow/GeoJSON cases.
