RFC-0059: Starlark as programmable middleware for vMCP#60
Conversation
Proposes extending vMCP's Starlark engine from composite-tool-only scripting into a unified programmable middleware surface, replacing the growing set of independent config knobs (optimizer, filter, rate limiting, PII scrubbing) with a single script per session.

Summary
Proposes extending vMCP's Starlark engine from composite-tool-only scripting into a unified programmable middleware surface. A single script per session controls tool publishing, handler decoration, and built-in capabilities (search, PII scrubbing, rate limiting) — replacing the growing set of independent config knobs that interact in surprising ways.
