Description

The TypeScript SDK (mem0ai/oss) crashes at load time with Cannot find module 'ollama' when users don't have the ollama package installed, even when using a completely different provider (e.g., Gemini, OpenAI). This happens because ollama and 9 other peerDependencies were missing from tsup.config.ts's external array, causing tsup to bundle them inline instead of treating them as external requires.

This PR adds all missing peerDependencies to the external array and includes a drift-prevention test that will fail if a new peerDep is added to package.json without being externalized in tsup.config.ts.

Fixes #3857

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

• Verified npm run build passes and bundle compiles cleanly

• Inspected dist/oss/index.js to confirm require("ollama") is a simple external require (2 lines), not the entire inlined package

• Confirmed all other newly externalized deps (@google/genai, @mistralai/mistralai, @supabase/supabase-js, etc.) are also externalized correctly

• Drift-prevention test validates every runtime peerDependency is present in the external array

• Reverse staleness test validates no orphaned entries exist in the external array

• Unit Test
