DX-1264: Update Exports & Add CI Tests

[ytkimirti]

This PR has three main changes:

• update eslint & exports in package.json
• fixing small errors in examples and adding extensive CI
• llamaindex is removed, as it was causing errors explained below

Since llamaindex is removed, we will release a major version (2.0.0)

Eslint & Exports

• Updated tsup config
• Updated exports field in package.json

NOTE: This should not bring any breaking changes with the old version. Here is the old and new output coming from the attw cli:

CI

The examples are first tested with a local build. Then, a release is made with ci tag and it's released. It's tested by deploying to Vercel and CF workers.

let's squash merge

well @CahidArda,

rag-chat version	llamaindex version	Vercel (npm)
1.6.4	0.5.24	❌ missing tiktoken_bg.wasm

The issue with missing tiktoken_bg.wasm on Vercel has been resolved as mentioned in this comment. After resolving this issue, the rag-chat application now works seamlessly on Vercel.

Hey @mrsamirr,

we can reconsider adding llama parser to rag-chat in the future, but we didn't want to make installing rag-chat require that much configuration at this time.

Thanks a lot on reporting your solution!
