Is your feature request related to a problem? Please describe

Currently, I use the goodreads option for import lists, but would like to be able to use Hardcover instead due to Goodreads API going down in the future and other personal reasons.

Describe the solution you'd like

Include Hardcover as an option in Import Lists. Hardcover does have an API that should make this easier

Describe alternatives you've considered

As described above I am currently using the Goodreads import list but would like to use Hardcover instead.

Anything else?

Hardcover API: Here

I strongly support this feature request and would like to briefly explain why it's valuable.

Use Case

I use both Hardcover.app for tracking books and Readarr for managing my collection. Currently, I must manually add books to Readarr after adding them to my "Want to Read" list on Hardcover, which is inefficient.

Why It Matters

• Goodreads API has been in a deprecated state for nearly 4 years, pushing users toward alternatives like Hardcover
• Hardcover.app offers a modern GraphQL API (docs: https://docs.hardcover.app/api/getting-started/) with all necessary endpoints for integration
• This integration would enable the same workflow currently available with Goodreads lists

Technical Viability

The integration would be similar to the existing Goodreads implementation, requiring:

• Authentication via Hardcover API tokens
• Fetching the user's "Want to Read" list
• Scheduled syncing on the standard import list schedule

I'm willing to help test this feature if developed or provide any additional information about my use case. This integration would significantly improve the workflow for users transitioning from Goodreads to more actively maintained platforms.
