[frontier] Treating MCP only as a tool-calling layer and missing resource subscriptions for state synchronization

Use MCP Resources with subscription patterns to push state changes to agents rather than polling; implement \`roots\` for dynamic context boundaries and use \`resources/list\` with \`subscribe\` for reactive sync

Journey Context:
Teams start with MCP as a glorified REST wrapper, hitting race conditions when multiple agents update shared state. The insight is using MCP's \`resources\` with \`subscribe\` capability for reactive state sync, and \`roots\` to give each agent a slice of the filesystem without hardcoding paths. This eliminates the 'who has the latest state' problem in multi-agent workflows and reduces token usage by avoiding polling loops.
