docs: update README to include Modal cloud compute feature

Enhance the README by adding a new section on offloading heavy or GPU work to the cloud using Modal. This update details how users can integrate Modal keys for running commands or scripts on-demand, with files syncing back to projects and compute costs tracked alongside model expenses. Additionally, the upcoming features section has been updated to remove the mention of remote compute, as it is now covered in the new Modal integration.

 - **Use any tool-capable AI model** — OpenAI, Anthropic, Google, xAI, Qwen, and more via one [OpenRouter](https://openrouter.ai/) account, or free local models via [Ollama](./docs/local-models-ollama.md). Switch per chat.
 - **Fuse multiple frontier models with [OpenRouter Fusion](./docs/openrouter-fusion.md)** — pick a Fusion preset (e.g. *Opus 4.8 + GPT-5.5 + Gemini 3.1 Pro*) and a panel of models deliberates while a judge synthesizes one answer, with combined pricing and DRACO benchmark scores shown right in the model picker.
 - **Stay organized with projects** — each with its own files, chat history, up to 10 parallel chat tabs, rich file previews (including bioinformatics formats), a LaTeX editor, and cost tracking with optional spend caps.
+- **Offload heavy or GPU work to the cloud with [Modal](https://modal.com)** — add your Modal keys and Kady can run a command or script on an on-demand sandbox, from a cheap CPU box up to H100 GPUs. Files sync back to your project and the compute cost is tracked right alongside model spend. Pick the instance per chat from the compute selector.
 - **Extend it with [MCP servers](./docs/mcp-servers.md)** — connect GitHub, reference managers, databases, and hundreds of other external tools.

 ## What's coming
 
-Literature search (Paperclip), document conversion, remote compute (Modal), browser automation, and the provenance/"Copy as Methods" export are being re-added in upcoming releases, along with MCP tools for sub-agents and a UI experience further tailored to scientific workflows. In the meantime, many of these are available today by connecting an [MCP server](./docs/mcp-servers.md).
