v0.3.0

What's New in v0.3.0

Major Features

• 5 AI Providers — Mistral, OpenAI, Anthropic, Gemini, and Ollama (local). Stream completions from any provider with hot-swappable model selection
• Semantic Search — Documents are chunked and embedded at upload time; queries are embedded at search time with vector cosine similarity, falling back to TF-IDF
• Ollama Auto-Detect — Automatically detects running Ollama instances on mount, dynamically fetches available models from /api/tags
• Multi-Provider Settings UI — Per-provider API key sections (Mistral, OpenAI, Anthropic, Gemini), Ollama URL + Connect button with live status indicator
• Provider-Grouped Model Selector — Colored dots in TopBar visually distinguish provider groups in the model dropdown

Quality & Reliability

• 191 Automated Tests — Full test suite covering stores (uiStore, ragStore, canvasStore), API config/providers, utilities, components, and hooks. All passing with Vitest + jsdom
• TypeScript Strictness — Replaced all any types with proper types (Message, inline API response types, catch clauses with instanceof Error)
• Bug Fixes — 6 bugs fixed during stress testing including missing finalize call in embed router, setContent typo in ProviderModelSelect, missing tools imports in providers, canvas.width typo in useOllamaDetect
• CSP Hardening — Content Security Policy enforced at the Tauri level; meta tag removed from index.html

Cross-Platform CI/CD

• GitHub Actions CI — Runs tsc --noEmit, vitest, and vite build on push/PR to main
• Cross-Platform Build Matrix — Automatic MSI/EXE (Windows), DMG (macOS), and AppImage (Linux) builds on tag push
• Download Links — README now lists platform-specific installer links
