…ay (SciML#564) Replace Base.Threads threading with Polyester @Batch in FastBroadcast VectorOfArray extension. When Polyester is loaded, the 3-way extension RecursiveArrayToolsFastBroadcastPolyesterExt provides threaded broadcasting using Polyester.@Batch. Without Polyester, threaded broadcasting falls back to serial to avoid issues with mixing Polyester and Base threading. Bump version to 3.54.0.

When Polyester is not loaded and a user requests threaded FastBroadcast
on VectorOfArray{SArray}, throw an error explaining they need to load
Polyester.jl. Also fix tests to use Vector-of-SVector construction
(not Matrix-of-SVector) to properly exercise the SArray-specific path.

When Polyester is loaded, RecursiveArrayToolsFastBroadcastPolyesterExt defines more-specific methods for AbstractVectorOfSArray that win dispatch, so the base ext's AbstractVectorOfArray fallback is only reached when Polyester is not loaded. The flag check was redundant. Co-Authored-By: Chris Rackauckas <accounts@chrisrackauckas.com> Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The Tests.yml workflow was only triggering on PRs to master, so PRs targeting v3-backport had no CI coverage. Add v3-backport to the branches list for both pull_request and push triggers.
