This PR extends WSH RPC command signatures to support `ctx + 2+ typed
args` while preserving existing `ctx` and `ctx + 1 arg` behavior. It
also adds a concrete `TestMultiArgCommand` end-to-end so the generated
Go/TS client surfaces can be inspected and exercised from CLI.
- **RPC wire + dispatch model**
- Added `wshrpc.MultiArg` (`args []any`) as the over-the-wire envelope
for 2+ arg commands.
- Extended RPC metadata to track all command arg types
(`CommandDataTypes`) and exposed a helper for normalized access.
- Updated server adapter unmarshalling to:
- decode `MultiArg` for 2+ arg commands,
- validate arg count,
- re-unmarshal each arg into its declared type before invoking typed
handlers.
- Kept single-arg commands on the existing non-`MultiArg` path.
- **Code generation (Go + TS)**
- Go codegen now emits multi-parameter wrappers for 2+ arg methods and
packs payload as `wshrpc.MultiArg`.
- TS codegen now emits multi-parameter API methods and packs payload as
`{ args: [...] }`.
- 0/1-arg generation remains unchanged to avoid wire/API churn.
- **Concrete command added for validation**
- Added to `WshRpcInterface`:
- `TestMultiArgCommand(ctx context.Context, arg1 string, arg2 int, arg3
bool) (string, error)`
- Implemented in `wshserver` with deterministic formatted return output
including source + all args.
- Updated `wsh test` command to call `TestMultiArgCommand` and print the
returned string.
- **Focused coverage**
- Added/updated targeted tests around RPC metadata and Go/TS multi-arg
codegen behavior, including command declaration for `testmultiarg`.
Example generated call shape:
```go
func TestMultiArgCommand(w *wshutil.WshRpc, arg1 string, arg2 int, arg3 bool, opts *wshrpc.RpcOpts) (string, error) {
return sendRpcRequestCallHelper[string](
w,
"testmultiarg",
wshrpc.MultiArg{Args: []any{arg1, arg2, arg3}},
opts,
)
}
```

This allows code generation to properly embed structs when embedded in
the original types. It affects the generation of `gotypes.d.ts` and
`metaconsts.go`.
Additionally, the `AiSettingsType` has been split off and embedded into
the original `SettingsType` to make schema generation easier.
