Replace @aws-sdk/client-s3 (~150 transitive deps, ~14MB) with aws4 (0 transitive deps, ~40KB) and Node.js built-in fetch+crypto for S3 ListObjectsV2 against Hetzner Object Storage. - New s3-client.ts: SigV4 signing via aws4, regex-based XML parsing with namespace tolerance, pagination support, 5 error categories - 29 unit tests (node:test, zero-dependency) covering signing, parsing, entities, missing fields, pagination, abort, errors - Settlement guard for double done(null) on abort - XML entity decoding and regex metacharacter escaping - Dependency surface: 150 packages → 1 (aws4, single-file, auditable)
