Summary

The README includes resource-specific API inventories and workflows that obscure SDK setup. Remove those sections and keep installation, authentication, a minimal example, and shared client behavior.

Why

Keep the repository landing page focused on using the SDK. The final change edits only README.md and CHANGELOG.md; it adds no documentation files or documentation-check changes.

Verification

• make lint, make build, make test, and go build ./examples/... — not rerun locally; no Go source or example changes.
• make docs-check passed during this change; generated API reference remains unchanged.
• Account-backed integration tests not required for this documentation-only change.

Also passed: README local-link and Markdown-fence checks, git diff --check, and python3 .github/scripts/release_notes.py check. No live examples were executed. CI will validate the updated commit.

Impact

• Public API or runtime behavior changed — no SDK source changes.
• Documentation change recorded under Unreleased in CHANGELOG.md.
• Generated API documentation or contract fixtures updated — neither is changed.
• Cross-SDK consistency considered across Go, Python, TypeScript, and Java.
• Breaking-change migration notes — not applicable.
• No credentials, .env.live, logs, or generated test output committed.
