Pull Request Overview
This PR fixes a bug in the promise-swr library where multiple concurrent calls could trigger multiple revalidations during the stale-while-revalidate process. The fix adds a check to prevent revalidation when one is already in progress.
- Adds a condition to prevent concurrent revalidations by checking
!cached.revalidating - Removes the debug dependency and all debug logging statements
- Improves TypeScript documentation with generic type parameters

This PR fixes a minor bug when revalidating in
promise-swr: If multiple calls to the wrapper were executed, multiple calls to the wrapped functionfncould be made during the time it would take to revalidate (34be133).Several other documentation and minor improvements were added.
