fix: Deny passing Buffer columns to SQLite JSON helpers

[hwisu]

Howdy 🖖,

This PR adds compile-time type checks to SQLite JSON helpers (jsonArrayFrom, jsonObjectFrom, jsonBuildObject) to reject Buffer/Uint8Array columns.

Passing binary values to JSON functions throws SqliteError: JSON cannot hold BLOB values. This change prevents that runtime error by catching it at compile time.

Changes

• Added HasUint8Array<T> and ObjectHasUint8ArrayProperty<O> type utilities

• SQLite JSON helpers now return KyselyTypeError when binary columns are detected

• Error message includes workarounds: eb.cast(column, "text") or sql`hex(column)`

  Example

  // ❌ Compile error - Buffer column detected
  jsonArrayFrom(
    db.selectFrom('person').select(['id', 'data'])  // data: Buffer
  )
  
  // ✅ Works - convert to hex string
  jsonArrayFrom(
    db.selectFrom('person').select([
      'id',
      sql<string>`hex(data)`.as('data_hex')
    ])
  )
