Adds Promptise Foundry (Python, Apache 2.0) as a high-level framework that covers both sides of MCP — so it belongs in both the ### For servers and ### For clients lists under ## 📚 Frameworks.

Promptise Foundry is the MCP framework for building secure, scalable MCP servers with real access control and a FastAPI-style developer experience. On the server side: JWT / RS256 / ES256 / API-key authentication, capability-based guards, a composable middleware chain (rate limiting, circuit breakers, caching, HMAC-chained audit, Prometheus, OpenTelemetry), dependency injection via Depends(), per-tool versioning, streaming, elicitation, sampling, and an in-process TestClient. On the client side: a native MCP implementation (no third-party MCP client deps) over stdio / SSE / streamable HTTP with bearer and API-key auth, automatic tool discovery, and unified routing across multiple servers.

Placed alphabetically within each list and formatted to match neighboring entries (FastMCP, ModelFetch, Quarkus MCP Server SDK, Spring AI MCP Client). CONTRIBUTING.md's rule against new server implementations does not apply — this is a framework listing, not a server.
