Feat: Add MCP server(s) for "share in, share out" workflows #108
Description
As a user, I want to use share information from other apps to SmolChat and viceversa. For example, I share a URL from my browser to SmolChat, ask it to summarize it and create a note that I can then share with an email application. Built-in MCP servers would provide the tools for the LLM to interpret the URL, fetch information, and package it in a way that Android recognizes can be used by email applications. This can be extended to include any use case tha can be addressed by sharing something with the application, interpreting it for the LLM, and deterministically generating an artifact that can be shared with other apps.
Being able to act as a launcher and open applications on demand would be nice, too.
