Summary

Remove two unused internal HTTP helpers, put and delete. Current Client Tool updates, uploads and deletions already use the response-aware paths. Supported SDK methods and behavior stay the same.

Cleanup 1 of 4, completed before starting the next cleanup.

Public behavior verified

• Existing public-interface and installed-consumer tests pass; no new test is needed for unused-code removal.
• Typechecking, all 123 SDK tests, and packed-package checks pass.
• Public exports, documentation and service compatibility are unchanged.
• No credentials or issued plaintext API Keys are included.

Evidence

Before: two internal helpers had no source, test, example or dynamic references. After: callers continue using the existing response-aware helpers and the SDK checks pass.

Merge Danger

Door: two-way. Blast Radius: internal SDK code. No API or deployment change.
