<!-- CURSOR_SUMMARY -->

> [!NOTE]
> **Low Risk**
> This PR only updates version, changelog, and Release Please manifest;
runtime risk depends on the already-merged #311 change, not these files.
> 
> **Overview**
> Release Please bumps **`launchdarkly_event_source_client`** from
**2.2.0** to **3.0.0** and records the semver-major release in the
monorepo manifest and package changelog.
> 
> The **3.0.0** entry documents the breaking behavior already landed in
[#311](#311):
**every SSE HTTP error response** is now surfaced on the event stream
with **status**, **headers**, and whether the failure is **recoverable**
(retry vs stop). Consumers that only handled success events or assumed
errors were silent must update their stream error handling; the major
version signals that contract change even though this PR’s diff is
mostly versioning and release notes.
