Minimalist AWS Client for Node.js

aws-client is a minimalist Node.js client library providing simplified access to a subset of AWS services. Currently, it supports core operations for DynamoDB (get, batchGet, put, batchPut, query) via `DynamoClient` and SNS (publish) via `SNSClient`. The package is at version 3.0.6 and appears to be actively maintained, with an ongoing migration of "v1 functions" to "v2 functions." A key differentiator is its focus on minimalism and efficiency: v2 functions leverage the modular packages of the AWS SDK v3 internally, reducing the overall dependency footprint compared to requiring the full `aws-sdk` package. However, users employing older "v1 functions" must still explicitly install `aws-sdk` as a peer dependency, a requirement that will be phased out as the migration completes.
