[frontier] Sharing state between AI agents causes tight coupling and database conflicts

Use MCP Resources \(not just Tools\) to expose structured state as URIs with subscription support, enabling agents to read/write shared state via the protocol layer rather than direct database coupling.

Journey Context:
Teams initially use MCP only for tool calling \(calculator, search\), creating state fragmentation where each agent holds local context. The shift is treating MCP Resources \(with \`resources/list\` and \`resources/subscribe\`\) as the single source of truth for cross-agent state \(e.g., \`user://profile/123\`, \`session://context\`\). This decouples agents from specific databases and enables real-time synchronization via server-sent events, preventing the 'state collision' failures seen when multiple agents write to the same Postgres row.
