Fix: package compatibility issues across platform and modules - [PLT-87136] [PLT-90390] [PLT-90489]

[Raina451]

SDK should be fully compatible across:

• Node.js
• Web browsers
• All bundlers (Webpack, Vite, Rollup, etc.)
• All frameworks (React, Vue, Angular, Next.js, etc.)
• Both ESM and CJS module systems

Issues:

• Single index.d.ts file was being used for both ESM and CommonJS, causing TypeScript to incorrectly identify the module format.
• Node.js-specific dependencies were breaking browser bundles
• Module Resolution Conflicts

Fix:

• Updated entry points: main → CJS, module → ESM with proper extensions
• added conditional exports with format-specific type mappings
• added optionaldependencies in package.json (npm installs them automatically but doesn't fail if installation fails (browser environments))
• Gets externalized by Rollup automatically (in our allDependencies array)

rollup.config.js

• Added UMD browser bundle with Node.js dependency exclusions

• Created separate type declaration builds (.mts, .cts, .d.ts)

• Added environment-specific bundling logic

• index.d.mts → ESM type declarations

• index.d.cts → CommonJS type declarations

• index.d.ts → Fallback for legacy tools

Removing unused pkg dependnecies from package.json
removing content-type from upload file method of buckets, as content type is not needed

Tested across:

• react (create react app)
• react + ts + vite
• vue
• webpack react
• nodejs
• nextjs
  • server side
  • client side
• cjs

Since we removed the content-type parameter from uploadFile method, we would need to update the comments on that method as well.
