chore: bump version to 0.5.2

- Fix pin icons in ConversationItem to use bookmark style matching TopNav
- Make pin() and archive() methods async with IndexedDB persistence
- Use optimistic updates with rollback on failure
- Queue changes for backend sync via markForSync()

 ## Features
 
 ### Chat
-- Real-time streaming responses
-- Message editing with branch navigation
+- Real-time streaming responses with token metrics
+- **Message branching** — edit any message to create alternative conversation paths
 - Markdown rendering with syntax highlighting
+- **Thinking mode** — native support for reasoning models (DeepSeek-R1, etc.)
 - Dark/Light themes
 
+### Projects & Organization
+- **Projects** — group related conversations together
+- Pin and archive conversations
+- Smart title generation from conversation content
+- **Global search** — semantic, title, and content search across all chats
+
+### Knowledge Base (RAG)
+- Upload documents (text, markdown, PDF) to build a knowledge base
+- **Semantic search** using embeddings for context-aware retrieval
+- Project-specific or global knowledge bases
+- Automatic context injection into conversations
+
 ### Tools
 - **5 built-in tools**: web search, URL fetching, calculator, location, time
 - **Custom tools**: Create your own in JavaScript, Python, or HTTP
+- Agentic tool calling with chain-of-thought reasoning
 - Test tools before saving with the built-in testing panel
 
 ### Models
 - Browse and pull models from ollama.com
 - Create custom models with embedded system prompts
-- Track model updates
+- **Per-model parameters** — customize temperature, context size, top_k/top_p
+- Track model updates and capability detection (vision, tools, code)
 
 ### Prompts
 - Save and organize system prompts
