fix: publish TypeScript types

[salza80]

Update the package build and publish metadata so TypeScript declarations are generated and included in the npm package.

The source exports TypeScript types, but the package did not emit or publish declaration files.

What changed

• Added a top-level types entry pointing to dist/main.d.ts
• Added a declaration-only TypeScript build via tsconfig.build.json
• Updated npm run build to generate both JS bundles and .d.ts files
• Added prepack so npm pack / npm publish build the distributable package before packaging
• Made Error.captureStackTrace optional so generated declarations do not leak Node-only ambient types

The first declaration build also exposed @types/node through inherited Error static fields, which could break consumers that do not install Node types. The dedicated declaration build avoids that leak.

Pull request overview

Updates the package build/publish setup to generate and ship TypeScript declaration files for the library’s public API, aligning runtime bundles (Vite) with published type definitions.

Changes:

• Added a declaration-only TypeScript build (tsconfig.build.json) and wired it into npm run build.
• Updated package.json to publish types via types + conditional exports, and added prepack to build before npm pack/npm publish.
• Adjusted AbstractError to use an optional Error.captureStackTrace to avoid leaking Node-only typings into generated declarations; updated Travis CI to Node 20 and to run the build.
