Align monaco-code-editor with Cosmos repo conventions and switch library build to tsup

[anil08607]

What Changed

• Replaced the old build step, which only typechecked, with a real tsup library build
• Published compiled artifacts from dist/ instead of exporting raw src/ files
• Added a shared tsup.config.ts with browser-targeted ESM output, declarations, sourcemaps, and CSS inclusion
• Kept Cosmos as the local preview/site workflow by adding matching scripts like start, build:site, cosmos-export, and vercel-build
• Updated package exports so consumers resolve dist/index.js, dist/index.d.ts, and the generated stylesheet

Why We Changed This

• The repo was using Cosmos for preview, but build was not producing a distributable package
• Publishing src/index.ts directly is inconsistent with sibling repos and can break downstream consumers expecting built JS and type declarations
• pcb-viewer and similar repos already separate concerns cleanly:
  • cosmos and cosmos-export for demos and site checks
  • tsup for npm package output
• Matching that convention makes this package easier to publish, preview, and maintain across the repo ecosystem
