fix(language): anchor responses to the user's language by default - #55

Conversation
Models occasionally drifted to the wrong language (e.g. Spanish replies in pt-BR sessions) because no language directive existed unless the user set settings.language. Now every system prompt path — including CLAUDE_CODE_SIMPLE mode — injects a locale-agnostic 'respond in the language of the user's most recent message' section, while the explicit settings.language override is preserved for users who want a fixed language. Bumps version to 0.15.25. Co-Authored-By: Verboo Code <noreply@code.verboo.ai>

Summary
settings.language.CLAUDE_CODE_SIMPLEearly-return — injects a locale-agnostic section: "Always respond in the same language as the user's most recent message…".settings.languageoverride is preserved (fixed-language behavior for those who want it); the picker hint now reads "Leave empty to respond in the user's language".Context
Root cause was verified across providers/router/CLI: nothing pinned or injected language anywhere. Model-side drift (DeepSeek V4 lost output-language self-monitoring; GLM-5.3 mixed languages) fills the gap when no anchor exists. Locale-agnostic by design — Verboo Code is international; no hardcoded locale.
