Full-suite repair, desktop cluster: FN-8926's Node-only
@fusion/core/mcp-builtin-servers subpath needed the same vitest alias
desktop's engine/dashboard siblings already carry — without it the broad
prefix alias mangled the path and the runtime-resolution test failed with
ENOTDIR. The release-workflow test pinned actions/setup-java to an exact
patch that Dependabot rotates (broke twice, #3303 then #3367); it now
asserts the v5 major while keeping the JDK-21 and Android wiring
assertions intact. Desktop suite: 29 files / 265 tests green.
