`@types/node` is pinned at `^12.20.33` in both `ui/packages/ce/package.json` and `ui/packages/shared/package.json`. Node 12 has been EOL since April 2022. Symptoms: - `pnpm install` warns about unmet peer deps from vitest 3.x and vite 6.x, both of which require `@types/node@^18.0.0 || ^20.0.0 || >=22.0.0`. - Dependabot keeps opening patch PRs within the EOL major (most recent: [#331](https://github.com/postgres-ai/database-lab-engine/pull/331), 12.20.33 -> 12.20.55), which fixes nothing. Proposed fix: bump `@types/node` to `^22` (current LTS) in both `ce` and `shared`. Verify build/tests after — runtime CI/Docker images already run modern Node, so this should be a pure type-level change. Closes [dependabot PR #331](https://github.com/postgres-ai/database-lab-engine/pull/331) once landed.
