Note

Overview
Release 6.0.0 — bumps the package and release tooling from 5.3.2 to 6.0.0 in .release-please-manifest.json, LaunchDarkly.EventSource.csproj, and PROVENANCE.md, and adds the 6.0.0 section to CHANGELOG.md.

The changelog records what ships in this major: breaking expansion of IEventSource with SetTemporaryRetryDelayBounds and ClearTemporaryRetryDelayBounds (custom implementers must add them; built-in EventSource callers are unchanged), SSE retry: field handling and runtime temporary retry-delay bounds, plus fixes for review feedback and interrupting pending backoff on shutdown. No application source changes appear in this diff—only version and release documentation.
