Bug

@ai-sdk/workflow: package.json points to files that aren't published

Reproduction

• Classified issue @ai-sdk/workflow: package.json points to files that aren't published #16925 as general library/package publishing behavior, not provider-specific behavior.
• Added examples/ai-functions/src/reproduction/workflow-require-entrypoint.ts to pack @ai-sdk/workflow@1.0.17, inspect the published tarball, and require it from a temporary node_modules install.
• The published tarball contains dist/index.mjs, dist/index.d.mts, and dist/index.mjs.map, while package.json declares ./dist/index.js for main and exports["."].require, plus ./dist/index.d.ts for types.
• The reproduction script observes require("@ai-sdk/workflow") failing with MODULE_NOT_FOUND for missing dist/index.js; this matches the expected issue behavior for CommonJS consumers while the import target exists.
