Enable minification to reduce bundle size

[yamcodes]

Summary

Enable minification in the build process to reduce bundle size by removing comments and minifying code.

Current State

• Bundle size: 711 B (minified and brotlied)
• Comments are included in the bundle
• Build output is not minified

Proposed Solution

Enable minification in tsdown.config.ts by adding minify: true. This will:

• Remove all comments from the bundle (JSDoc comments remain in source files for TypeScript)
• Minify the JavaScript code
• Reduce bundle size

Expected Outcome

• Smaller bundle size
• Comments removed from production bundle (but preserved in source for TypeScript tooling)
• Improved code readability in bundle (minified)

Notes

JSDoc comments will remain in source files for TypeScript type checking and IDE hints, but will be stripped from the bundle during minification.
