fix(factories): infer typed array elements as Binary

[kentkwu]

Summary

Infers arrays of typed arrays as proper Arrow types, so vectorFromArray([uint8Array, ...]) produces a Binary vector instead of a struct with one Float64 field per byte.

The problem

Type inference treated typed arrays as plain objects and built a struct from their index keys. An array of 16-byte Uint8Array values became Struct<{0: Float64, ..., 15: Float64}> instead of Binary. The output was also lossy: values of different lengths were padded with nulls to the longest one, and the static type resolved to never.

Behavior change

This changes the inferred type for these inputs, but it's a bug fix: the old output didn't preserve the input values and didn't match its own static type. Code that needs a specific type can still pass one explicitly to vectorFromArray.

Changes

• vectorFromArray infers Uint8Array (and Node Buffer) elements as Binary, and other typed arrays as List of their element type (e.g. Int32Array → List<Int32>)
• tableFromArrays and tableFromJSON pick this up for columns and struct fields, so tableFromArrays({ values: [[bytes, bytes]] }) gives List<Binary>
• JavaScriptArrayDataType resolves to the same types at compile time instead of never
• Mixed typed array kinds and DataView elements throw the existing "explicit type declaration expected" error

Test Plan

• npx jest -c jestconfigs/jest.src.config.js test/unit
• npx eslint src/factories.ts src/interfaces.ts test/unit/vector/vector-tests.ts
• Checked inferred static types for Uint8Array, Buffer, Int32Array, Uint8ClampedArray, and BigInt64Array with tsc
