fix: remove editorial parenthetical descriptions from product names (#1778)

Community PRs repeatedly add marketing commentary in parentheses next to
product names (licensing model, parent company, architecture). Product
listings should contain only the product name.

Cleaned across 8 files in 5 languages (EN, KO, JA, ZH, PT) plus
install.js code comments and CHANGELOG. Added static analysis guard
test that prevents this pattern from recurring.

Fixes #1777
