TL;DR: every workflow runs Bun 1.4.3 instead of 1.4.2.

• 1.4.3 fixes the bun test --isolate segfault when a finished test file's global is collected while FinalizationRegistry callbacks are still queued (Cancel a dead realm's deferred work at the end of the collection that found it dead oven-sh/bun#44279). Our CI crash has the same stack; fix(docx): close display-list handles instead of leaving them to finalizers #1323 avoids it on 1.4.2 by disposing wasm handles eagerly.
• The node:vm repro from Cancel a dead realm's deferred work at the end of the collection that found it dead oven-sh/bun#44279 segfaults 10/10 on 1.4.2 and 0/10 on 1.4.3 (Linux x64).
• CI's test step on main, 4 vCPU Linux VMs, arms interleaved: no segfault on either; failed tests per run 16, 4, 7, 1, 5, 6 on 1.4.2 vs 7, 2, 0, 1, 0, 0, 0 on 1.4.3; median wall time 1189 s vs 1157 s.
• scripts/native-bindings.test.ts expects the new pin.

Bump CI Bun runtime from 1.4.2 to 1.4.3 across all workflows
Safe to merge: mechanical version bump with matching test expectations and no remaining workflow pins on 1.4.2.

Summary:

• Updates bun-version to 1.4.3 in 9 workflow files (ci, deploy, e2e, macos-app, native-dist, native-packages, publish-native, release, visual-fidelity).
• Updates the two pinned-version assertions in scripts/native-bindings.test.ts to expect 1.4.3.
