• Replaces rollup with rolldown across the build system
• Updates from @swc/core minification to oxc-minify
• Migrates from rollup-plugin-dts to rolldown-plugin-dts for type declaration bundling
• Updates oxc-parser and oxc-transform to v0.105.0 to match rolldown compatibility

Inconsistent import path for replacePlugin. This file imports from rolldown/experimental while scripts/create-rolldown-config.js imports from rolldown/plugins. These should use the same import path for consistency. Please verify which is the correct import path for [email protected] and update both files to use the same path.

Suggested change

	import { replacePlugin } from 'rolldown/experimental'
	import { replacePlugin } from 'rolldown/plugins'
