fix(openapi-typescript-helpers): keep index.d.cts in npm distribution

[yukukotani]

Changes

Fix #1749

By default, npm publish respects .gitignore so that the npm distribution doesn't include index.d.cts.

package.ison points to it even though it's missing, and this results in fallback to index.cjs. This causes that types from openapi-typescript-helpers to be treated as any.

This PR adds files field in package.json to explicitly declare index.d.cts to be included in the distribution.

How to Review

The output of npm pack includes package.d.cts.

Checklist

• Unit tests updated
• docs/ updated (if necessary)
• pnpm run update:examples run (only applicable for openapi-typescript)

Ah, thank you! I hadn’t considered the .gitignore impact on publishing. Thank you for fixing it!
