[Feature] Improve documentation for setup

[Open-Source-you]

Is your feature request related to a problem? Please describe.
New contributors face confusion when setting up the project locally.

Describe the solution you'd like
Expand the README and add an INSTALLATION.md with step-by-step setup, dependencies, and troubleshooting tips.

Describe alternatives you've considered
Inline code comments are helpful but not sufficient for onboarding.

Additional context
Clearer documentation will lower the barrier for first-time contributors.
