Lau Setup 1.4.1 installer-only compatibility hotfix

What changes

Lau Setup 1.4.1 recognizes installed enGB, ptBR, and itIT 3.3.5a clients. It preserves the client-selected locale and writes only the normal Lau-managed root and matching active-locale targets.

The release catalog maps those three clients to the existing verified English visual assets. This avoids a false “missing matching language files” rejection while keeping the mapping visible, reviewable, and testable in release metadata.

What does not change

• Game release remains 3.0.9 Lau; /pyversion remains 3.0.9.
• The nine existing localized game locales and their assets are unchanged.
• This does not install a base language pack, alter WTF\\Config.wtf, rename archives, or add Portuguese or Italian game-text translations.
• No DBC edits.
• Existing server-specific visual reports and map/loading-screen reports remain backlog items.

Validation performed and production scope

• 74 Windows isolated regression groups passed, including install, repeat-install, option-switch, interrupted-operation, exact restore, and configured-locale coverage for enGB, ptBR, and itIT.
• Readback tests prove English visual source assets reach only the selected locale’s managed targets.
• The packaged ZIP and source archive were verified before publication.

Runtime validation for a representative real enGB, ptBR, and itIT client is intentionally deferred to production feedback for this edge-case installer hotfix. Report the exact client folder layout, locale, selected options, installer log and a screenshot if a compatibility path fails.
