Add internationalization support to the MiroFish frontend with Chinese (zh-CN) as the default language and English (en) as an alternative, switchable via a toggle button in the header. Changes: - Install vue-i18n and configure with Composition API mode - Create zh-CN and en locale files with ~262 translation keys - Add useLocaleToggle composable for shared language toggle logic - Replace hardcoded Chinese strings with $t() calls across all 14 Vue components and 7 views - Add language toggle button to all page headers - Persist language preference in localStorage - Configure Vite @ path alias for clean imports Chinese regex patterns that parse backend LLM responses are intentionally preserved unchanged (Step4Report.vue, Step2EnvSetup.vue). Also fixes API base URL to use window.location.hostname instead of hardcoded localhost, enabling remote access.

The Home page navbar is transparent (not dark as assumed), so the white-on-transparent button was invisible. Use explicit light gray background with dark text for guaranteed visibility on any background. Also increase button size across all views for better discoverability.

Pass the user's language preference (from Accept-Language header) through the backend to all LLM prompt generation, so agent profiles, simulation configs, and prediction reports are generated in the user's chosen language. Changes: - Frontend: attach Accept-Language header to all API requests via axios interceptor (reads from localStorage mirofish-locale) - Backend: new app/utils/i18n.py with locale helpers - Profile generator: bilingual prompts for individual and group personas - Report agent: English versions of plan, section, and chat prompts - Simulation config generator: bilingual time/event/agent config prompts - Interview prompt: locale-aware prefix - API routes: capture locale before background threads, pass through the entire call chain Locale flow: API endpoint -> captured before thread -> SimulationManager -> OasisProfileGenerator / SimulationConfigGenerator / ReportAgent Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Time/event/agent config progress messages and reasoning labels were hardcoded in Chinese. Now locale-aware. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- ReportLogger: all log messages now bilingual (planning start/complete, section start, react thought, report complete) - generate_report(): all progress callbacks bilingual - Step4Report.vue: panorama/insight/interview/search display labels translated via $t() calls (active memories, historical memories, entities, expand/collapse, tabs, etc.) - Added 28 new step4.* locale keys for tool result UI Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Extends the frontend i18n work from #244 to the backend — LLM-generated content (agent profiles, simulation configs, prediction reports) and all progress/status messages now respect the user's language preference.
Depends on: #244 (frontend i18n with vue-i18n)
