First release. A single static binary that sits in front of one or more
MCP servers over Streamable HTTP and adds, with zero backend changes:
circuit breaking, jittered retries, token-bucket rate limiting,
min-deadline-threshold enforcement, panic isolation, JSON Schema
validation of tool arguments, response size clamping, bearer/API-key
auth, Prometheus metrics, and structured slog logging — all driven by
one YAML config, matched per tool by glob pattern.

See README.md for the quick-start and BENCHMARKS.md for measured
performance numbers.
