Overwatch with React in SSR

[karandeepsingh7070]

Description
Currently, there is no clear, practical example showing how to use Overwatch with React in SSR environments (Next.js, Remix, or custom SSR setups) in the documentation or README.

This can make it challenging for developers to confidently adopt Overwatch in production SSR projects, as SSR usage patterns (initial state hydration, avoiding client/server mismatches, etc.) are often non-trivial.

Request:

Add a dedicated "Using Overwatch with SSR" section in the documentation.

Include a minimal, working React SSR example (e.g., with Next.js app/ directory) showing:

Server store initialization and hydration.

This will help developers quickly understand and adopt Overwatch in real-world SSR applications.
