fix(registry): schema conformance

Fix the usage of `exclusiveMinimum`:

Ffor the “chainId”, “blocks.estimateBlockTime”, “grpcUrls.concurrency”, “retry.maxRequests”, and “retry.baseRetryMs”), the keyword `exclusiveMinimum` is given a numeric value. In JSON Schema draft‑07 the `exclusiveMinimum` keyword is of type boolean, and is used with a separate `minimum` value as this enforces a strict inequality.
