Resolves N.A

Description

What is the purpose of this pull request?

This pull request:

  • Implements the differential entropy calculation for the hypergeometric distribution (@stdlib/stats/base/dists/hypergeometric/entropy).
  • Utilizes robust Kahan-Babuška summation (@stdlib/stats/incr/sum) to ensure numerical stability and accuracy.
  • Adds comprehensive unit tests covering edge cases, parameter validation, and correctness checks against known values.
  • Adds TypeScript definitions (index.d.ts, test.ts) and benchmarks (benchmark/benchmark.js).
  • Includes complete documentation with runnable examples and REPL help text.
  • Updates the parent package (@stdlib/stats/base/dists/hypergeometric) to export the new entropy function.

Hi team, just bumping this gently as the workflows are still pending approval for a first-time contributor. I’ve verified the tests pass locally. Thanks!

Hi team, checking in one more time! No rush on the full code review, but whenever someone has a chance to approve the workflow runs for this PR, that would be awesome so we can get the CI checks out of the way. Everything is passing on my local machine. Thank you!
