Build pipeline runs both tsup and Vite, causing redundant outputs

[gupta-8]

Enhancement

Problem

The build script runs both:

• tsup (JS bundles + DTS)
• vite build in library mode

This can generate duplicate or unclear build artifacts.

Impact

• Larger and potentially confusing dist/ output.
• Harder to maintain and reason about published bundles.
• Risk of mismatched entrypoints over time.

Location

• package.json → scripts.build
• tsup.config.ts
• vite.config.ts

Suggested Improvement

Pick a single build strategy:

Option A

• Use tsup for JS + type declarations.
• Copy CSS assets manually.
• Remove vite build from the library build step.

Option B

• Use Vite library mode exclusively.
• Ensure it outputs both ESM and CJS if required.
• Align exports with Vite’s output.
