Q&A: setup, issue assignment, and PR help

[Abhash-Chakraborty]

Ask setup and contribution questions here when you are blocked and no specific issue thread fits.

Before asking, please include:

• Your OS and setup path: full Docker, light Docker, or manual local.
• The command you ran.
• The exact error message or screenshot summary.
• Which issue or PR you are working on, if any.

For code review feedback, continue the conversation on the PR itself.
