Add Croatian (hr) to voice dictation supported languages

Feature Request

Voice mode currently supports ~20 languages (Czech, Danish, Dutch, English, French, German, Greek, Hindi, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, Turkish, Ukrainian) but Croatian (hr) is missing.

Current behavior

• /voice hr is accepted as a command but the dictation language stays en
• /config has no dictationLanguage option to override this
• Speaking Croatian into voice mode produces garbled or no transcription

Expected behavior

Croatian (hr) should be available as a dictation language, either via /voice hr or through a config setting.

Context

• Croatia has 4+ million speakers and an active developer community
• Croatian developers are building production software with Claude Code (ERP integrations, e-invoicing standards, etc.)
• Croatian is a Latin-script language with clear phonetics — should be relatively straightforward to add

Environment

• Claude Code version: 2.1.81
• OS: Windows 11 Pro
