📄 Description

…crash

start.sh runs with set -euo pipefail, but the playwright-install branch references ${WEB_LOADER_ENGINE,,} without a :- default. Containers that don't set WEB_LOADER_ENGINE in their env — the default for every deployment that isn't explicitly using playwright/firecrawl/tavily — crash on startup with:

start.sh: line 15: WEB_LOADER_ENGINE: unbound variable

Introduced by 070ab2650 (refac: reorganize scripts and ci workflows). Every other env-var reference in start.sh already uses :-; this one was missed because bash's ,, lowercase expansion can't be combined with :- in a single substitution. Splitting into two steps keeps the lowercase comparison intact.
