SBOL Data Lab — UI not built

The server is running, but the embedded TypeScript UI was not compiled into this binary.

Likely causes:

• Node.js (npm) wasn't on PATH at build time.
• SBOL_DB_SKIP_UI_BUILD=1 was set during the build.
• The crates/sbol-db-ui/ui/ source tree was missing.

Rebuild with Node 20+ available:

cargo build --release -p sbol-db

Or disable the lab entirely with SBOL_DB_LAB_ENABLED=false.
