[frontier] How to expose structured data to AI agents without tool call overhead

Use MCP Resources \(not just Tools\) to expose read-only structured context; subscribe to resource updates via MCP notifications for live data instead of polling tools

Journey Context:
Developers overload Tools for static data reads \(getFile, getSchema\), causing unnecessary latency and confusion. MCP Resources are first-class read-only entities with URIs and MIME types, designed for documents, git history, database schemas. Unlike Tools which execute code, Resources are cached and can be pushed via notifications. This separates read patterns from action patterns, reducing token consumption and clarifying agent intent. The tradeoff is that Resources are read-only; any write must still be a Tool.
