Remove unknown from basehandler.ts

[joyguptaa]

Issue Description

Currently, we do dev: data.find((item) => item.name === "dev") as unknown as DevFlag to override the type of dev. Implement this without using unknown as it is not the preferred way of doing so.

Expected Behavior

dev should auto-infer its type from its parent instead of overriding it

Current Behavior

To provide the type of dev we use as unknown as DevFlag
