v0.2.0-beta

This beta release expands ChatKnot with major usability, reliability, and multimodal improvements for real-world MCP + AI workflows.

• 📤 Rich Chat Export: Export any conversation as PDF, Markdown, or JSON with configurable tool input/output inclusion.
• 🖼️ Multimodal Chat Input: Attach images and files directly in chat, with model-capability-aware filtering to prevent unsupported payloads.
• 🧠 Smarter Model & Prompt Runtime: Requests now use two system instructions (user prompt + app default instruction), improving clarity and maintainability of agent behavior.
• 🧩 Capability-Aware Tooling: Model capability tags (vision, tools, file) are shown in selectors, and MCP/tool payloads are automatically gated by model support.
• 🛡️ Startup Safety Hardening: Health checks now proactively validate AI providers and MCP servers, auto-disable unreachable endpoints on network issues, and surface clear warning reasons.
• 🔐 Broader Provider Compatibility: Improved OpenAI-compatible endpoint handling with safer model discovery fallbacks and auth-header compatibility for protected proxies.

Full technical details are available in CHANGELOG.md.
