with PostHog/posthog#28564, we now start to respond different with the /decide and /local_evaluation APIs if users have gone over their quota limit. Now we need to change the SDKs to handle these new responses.

PR Summary

This PR adds support for handling quota limits in PostHog's .NET SDK, responding to changes in the /decide and /local_evaluation APIs when users exceed their quota limits.

  • Added QuotaLimited property to DecideApiResult in /src/PostHog/Api/DecideApiResult.cs to track which features are quota-limited
  • Implemented quota limit handling in /src/PostHog/PostHogClient.cs to return empty dictionaries for bulk flag requests when limits are hit
  • Added quota limit checks in DecideAsync() method to handle feature flag quota limitations
  • Added debug logging for quota exceeded scenarios with appropriate messages
  • Added comprehensive test coverage in /tests/UnitTests/Features/FeatureFlagsTests.cs for quota limit scenarios

@haacked thanks! I was working on it locally but my .NET LSP isn't playing nicely so it's been a pain. Thanks for helping, lmk if you have questions about the implementation!

When attempting a local evaluation API call that is quota limited, I assume we don't want to fallback to /decide correct? If one is quota limited, do we assume the other is too? Or should we continue to fallback to /decide?

@dmarticus I also noticed the log level for quota exceeded is Debug in this PR. I'm thinking this is something a consumer would want to notice. It should probably be Warning or Error. Right?

Yup, we should short-circuit if we get a local eval call that's quota limited

Yeah, let's go with a warning log, that's what the other PRs do.
