docs: update outdated tech stack and test instructions in README.md and DEV.md

[root-sarvesh]

Issue: Outdated Documentation in README.md and docs/DEV.md

Summary

Parts of the documentation (README.md and docs/DEV.md) are outdated and do not match the current codebase, tooling, or scripts. This may cause confusion and setup issues for new contributors.

---

Problems

1. Outdated Tech Stack Information in README.md

README.md still references:

• TypeScript 4

• React 17

• Vite 4

• Jest

• Cypress

But the actual repo uses:

• TypeScript 5

• React 18

• Vite 6

• Vitest (not Jest)

• No Cypress configuration

This mismatch misleads contributors setting up or extending the project.

---

2. Incorrect Test Commands in DEV.md

DEV.md instructs users to run:

npm run test:unit

npm run test:e2e

However, these scripts do not exist in the current root package.json.

The real command is:

npm run test

This causes confusion and failed setup attempts.

---

3. README.md Still Mentions Jest & Cypress

The repo uses Vitest, not Jest.
No Cypress e2e testing setup exists.

These entries need removal or correction.

---

Consequences

• New contributors may follow incorrect commands → setup failures

• Docs describe tools that the repo no longer uses

• Testing instructions do not work as written

• Tech stack section does not reflect reality

• Creates onboarding friction and unnecessary questions

Fixing this will improve clarity, reduce confusion, and keep the documentation aligned with the actual monorepo structure.

---

Expected Fix

• Update documentation to match the current codebase:

• Update tech stack details (TypeScript 5, React 18, Vite 6, Vitest)

• Remove outdated references (Jest, Cypress)

• Update test commands in DEV.md to correct ones

• Clarify that project uses Vitest

• Remove instructions for scripts that no longer exist

---

Files Affected

• README.md
