Greptile Summary

This is a focused patch release (0.27.0 → 0.27.1) that adds a files field to package.json so that only the built output (dist/) and TypeScript declarations (types/) are published to npm, keeping source files out of the package tarball.

• package.json: Version bumped to 0.27.1; files: [\"dist\", \"types\"] added — correctly matches the main, module, and types entry points already declared in the manifest.
• src/client.ts: x-sdk-version request header updated to 0.27.1, keeping the SDK self-identification in sync with the published version.
• CHANGELOG.md: New 0.27.1 section documents the fix clearly.
• package-lock.json: Regenerated lockfile reflecting the version bump; several @expo/cli nested peer-dependency entries were deduplicated and @babel/traverse had its peer flag dropped — both are normal side-effects of re-running npm install.

No logic or behavioral changes were made to the SDK itself.

Confidence Score: 5/5

Safe to merge — minimal, correct patch-level change with no behavioral impact on the SDK.

All changes are version-bump bookkeeping (package.json, package-lock.json, client.ts header) plus a straightforward files field addition that correctly restricts npm publish artifacts. No logic changes, no P0/P1 findings.

No files require special attention.

Important Files Changed

Filename	Overview
package.json	Version bumped from 0.27.0 to 0.27.1; files field added to restrict npm publish to dist and types directories only — the primary fix in this PR.
src/client.ts	Single-line change: x-sdk-version header value bumped from 0.27.0 to 0.27.1 to match the new package version.
CHANGELOG.md	Adds a 0.27.1 section documenting the files field fix.
package-lock.json	Lockfile regenerated: version bumped to 0.27.1; several @expo/cli nested peer-dependency entries removed/deduplicated; @babel/traverse peer flag dropped — all consistent with a normal npm install after dependency changes.
