Subject: [PATCH] fix: add .js extensions to relative imports for ESM
 compatibility

TypeScript compiler preserves bare module specifiers in compiled output,
which breaks ESM resolution in Node.js environments (Next.js, Mastra).
Add explicit .js extensions to all relative imports so the compiled
dist/ output works correctly as an ES module package.
