RecursiveArrayTools 4.5.4 → 4.5.5

Bumps version in Project.toml. Merged since v4.5.4 (the latest version in the General registry):

• Allow JET 0.12 in the QA environment for Julia 1.13 #682 Allow JET 0.12 in QA/NoPre test environments (tests/docs/CI only, not shipped)
• Allow KernelAbstractions 0.10 #679 Allow KernelAbstractions 0.10

Compare: 859e017...76bec79

Patch: allows KernelAbstractions 0.10 in [compat]; no source change.
Default-branch CI: the SciMLSensitivity Core4 downstream failure is the known Enzyme mi2 !== nothing assertion on Julia 1.13.2 (EnsembleThreads); that job resolved KernelAbstractions 0.9.45, so the compat change was not exercised. https://github.com/SciML/RecursiveArrayTools.jl/actions/runs/38819764786/job/116713203524

Risk assessment

• Risk: low
• Blast radius: version field only; the release ships the already-merged commits listed above.
• Evidence: version-line-only diff; default-branch CI on the shipped commit checked for regressions against the last release commit.
• Independent review: codex-cli 0.162.1 + gpt-6.1-sol rated it low, high confidence: Version-only PR releasing a compat widening and test-environment changes; no breaking changes or new public features. (read-only review, verdict MERGE)
• Merge: auto-merge candidate (version bump, master release duty)
