Pull request overview

This PR merges next into master, bringing in dependency/version bumps across the monorepo, significant improvements to ekscss source-map generation (including nested @import handling and interpolation tracking), and adds/expands Bun-based test coverage for multiple plugins and sourcemap behavior.

Changes:

• Update ekscss sourcemap implementation to track interpolation positions, support shifting mappings, and remap nested @import source maps.
• Add/expand tests (and snapshots) for sourcemaps plus plugin-import, plugin-apply, and plugin-prefix.
• Bump versions and devDependencies across packages; update Bun/esbuild/rollup/Svelte/PostCSS toolchain configs and lockfile.

• This snapshot file defines the same snapshot key twice (encoded map after addMapping following shift keeps both 1). The later exports[...] overwrites the earlier one; remove the duplicate block so there is exactly one definition per snapshot name.
