Greptile Summary

This is a focused patch release (0.27.0 → 0.27.1) that fixes the npm publish configuration by adding a files field to package.json, ensuring only the compiled dist/ and TypeScript declaration types/ directories are included in the published package rather than the full repository contents.

• package.json: Version bumped to 0.27.1; files field added with ["dist", "types"] — correctly scopes the npm package to built artifacts and type declarations only. npm's implicit inclusions (package.json, README, LICENSE) are always added automatically, so nothing is missing.
• src/client.ts: x-sdk-version request header updated to 0.27.1 — consistent with the package version.
• CHANGELOG.md: New entry added for 0.27.1 accurately describing the fix.
• package-lock.json: Version bumped and several new @babel/* helper packages appear as peer dependency resolutions — this appears to be normal lock-file churn from dependency resolution and all entries are marked "peer": true.

Confidence Score: 5/5

Safe to merge — changes are minimal, well-scoped, and consistent across all relevant files.

All changes are straightforward: a version bump, a one-field addition to package.json with the correct directories, a matching header update in client.ts, and a corresponding CHANGELOG entry. No logic changes, no API surface changes, and no regressions are introduced.

No files require special attention.
