Subject: [PATCH] fix(ui): increase Node memory limit for tsup build to prevent
 CI OOM errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Set NODE_OPTIONS='--max-old-space-size=4096' in build script
- Prevents "JS heap out of memory" during TypeScript declaration generation
- CI was failing when building 20+ components simultaneously
- Also simplified tsup DTS config (removed composite false workaround)

Fixes GitHub Actions build failures for @tpmjs/ui package.
