Merged in the 2026-09-16 sweep of the maintainer's own open PRs, at the owner's explicit instruction. No push was made to the PR branch: the merge took the head as the owning session left it (verified OPEN, non-draft and MERGEABLE against the release tip immediately before merging).
Release v3.8.24 — see CHANGELOG.md [3.8.24] for the full notes and the PR description for the contributors hall. Integration of release/v3.8.24 into main.
* fix(sse): defer enqueuing of event lines to align event names with data lines and prevent stop-signal event name misattribution
* fix(sse): preserve keep-alives and prevent pending event leakage on dropped chunks
* fix(sse): preserve pending event lines before other non-data lines and fix zero-window-size bypass
* fix(sse): defer lastEventLine update until after flush check to preserve previous event context on flush
* fix(sse): flush trailing pendingEventLine when stream closes
* fix(sse): preserve consecutive event lines without intervening data
