Description

Description
This PR introduces a

bookCount
virtual field to the

Author
type. Previously, to find out how many books an author had written, clients had to fetch the entire list of books and count them manually. This enhancement provides a direct, efficient way to retrieve the total count.

Summary of changes:

GraphQL Schema: Added bookCount: Int to the

Author
type definition.

BookController
: Implemented a @schemamapping method

bookCount(Author author)
that calculates the size of the author's book collection.
Performance: This allows clients to query for high-level statistics without the overhead of downloading full book details.
Closes keploy/keploy#3890

How Has This Been Tested?

The changes were verified manually using curl against the local GraphQL endpoint.

Test Case: Fetching Author Statistics

Setup: Ensure an author exists with multiple books assigned.
Execution: Run the following curl command:
bash
curl -X POST http://localhost:8081/graphql
-H "Content-Type: application/json"
-d '{"query": "{ getAllAuthors { firstName lastName bookCount } }"}'
Expected Result: The API returns the authors with a

bookCount
integer representing the number of books they are associated with.

Additional Context (Please include any Screenshots/gifs if relevant)

This is a non-breaking enhancement that improves data efficiency for UI components like author lists or profile summaries where only the count is required.
