MCPorter 0.9.0: Runtime Tool Filtering, Windows OAuth Fix, and Sturdier Stdio

Peter Steinberger ships MCPorter 0.9.0 — per-server allow/block tool filters, a Windows OAuth URL-quoting fix, schema-aware string coercion, and tougher stdio child-process shutdowns. Small release, sharp edges removed for anyone calling MCP servers from TypeScript or the CLI.
