Receives arguments as JSON plus a `next` callback and its context. Call `next_fn(args, next_ctx)` to invoke the next layer in the middleware chain, or return directly to short-circuit. The `result` and optional `annotation` fields are passed to the remaining middleware and application; `pending_marks` are Relay-owned lifecycle metadata emitted after the tool-end event and are not included in the application-visible result. The returned JSON must contain a `result` field and may contain `annotation` and `pending_marks` fields. The returned string must be allocated with `malloc` or an equivalent allocation compatible with `nemo_relay_string_free`. Ownership transfers to Relay when the callback returns; the callback must not free or reuse the string afterward, and Relay frees it exactly once.

Call this from an intercept to invoke the next layer (or original function). The returned string contains a serialized `ToolExecutionResult`. `next_ctx` is borrowed and valid only until the intercept callback returns; callers must not retain it or invoke `next_fn` asynchronously. The returned string belongs to the caller and must be released with `nemo_relay_string_free`.
