background-update-check.ts was using runBunInstall() which defaults to outputMode:"inherit", leaking bun install stdout/stderr into the background session. Reverted to runBunInstallWithDetails({ outputMode: "pipe" }) and explicitly logs result.error on failure.
Restores the accidentally deleted test case asserting that sibling dependencies (e.g. other:"1.0.0") are preserved in package.json after a plugin version sync.
