Update to go-sdk v1.7.0 and drop two committed binaries

Browse source 
v1.7.0 shipped on 2026-07-27, so the pin moves off v1.7.0-pre.3.

Removes mcp-client-go.exe and weather-server-go/weather.exe, which were
committed by accident in the previous commit — 14MB of build output that
should never have been in the tree. The tests branch adds the ignore rules
that keep them out.

Also from review: the server README claimed both tools set an OutputSchema.
Only get_alerts does; get_forecast relies on inference from the handler
return type, which is the idiomatic spelling and worth saying so.

@ -20,6 +20,8 @@ The server will communicate via stdio and expose two MCP tools:
## Structured output
Both tools declare an `OutputSchema` and return `StructuredContent`. `get_forecast` returns an object; `get_alerts` returns a top-level JSON array, which protocol revision `2026-07-28` is the first to allow — see [Structured Content](https://modelcontextprotocol.io/specification/draft/server/tools#structured-content) in the spec.
Both tools advertise an `outputSchema` and return `StructuredContent`. `get_forecast` returns an object; `get_alerts` returns a top-level JSON array, which protocol revision `2026-07-28` is the first to allow — see [Structured Content](https://modelcontextprotocol.io/specification/draft/server/tools#structured-content) in the spec.
`get_forecast` sets no `OutputSchema` on the `Tool`: the SDK infers one from the handler's return type, which is the idiomatic Go spelling. `get_alerts` overrides it, because inference widens a slice to `["null", "array"]` — a nil slice marshals to `null` — and the tool never returns nil.
Note that an array-rooted schema requires a `2026-07-28` client: the SDK sends it as written on every connection rather than projecting it down, so an older client rejects the tool list.
