v0.2.1

Changed

• Updated default model from gemini-2.5-flash to gemini-3.5-flash after demonstrating stability in real-world tests.

Fixed

• Fixed ICU plural syntax warnings caused by overlapping categories (e.g., having both =1 and one) in target translations.
• Added base-language fallback (e.g., pt for pt_BR) for target locales to enforce CLDR category validations correctly.
