Improve SignalR client deserialization and docs

- Enhanced error handling in streaming methods of AcSignalRClientBase: deserialization errors are now logged and skipped instead of throwing.
- SignalResponseDataMessage.GetResponseData<T>() now throws InvalidCastException on type mismatch (was silent/null before).
- Updated README to document new casting and error behavior.
- Added Bash(dotnet workload *) command to settings.local.json.
- Removed GeneratedCode attribute from LocationType.cs.

 ### Client
 - **`AcSignalRClientBase.cs`** — Abstract SignalR client managing `HubConnection`, request/response tracking via pooled `SignalRRequestModel`. `SendCoreAsync` builds `SignalParams` (with `IsRawBytesData` when `T == byte[]`). CRUD helpers (Post, Get, GetAll, GetAllInto). Configurable timeouts.
-- **`IAcSignalRHubClient.cs`** — Client interface + `SignalResponseDataMessage` (sealed, `RawResponseData` is `object?` — typed object or byte[], `GetResponseData<T>()` direct cast). Legacy message types (`IdMessage`, `SignalPostJsonDataMessage`) marked `[Obsolete]`.
+- **`IAcSignalRHubClient.cs`** — Client interface + `SignalResponseDataMessage` (sealed, `RawResponseData` is `object?` — typed object or byte[], `GetResponseData<T>()` safe `is T` cast — type-mismatch returns null, does **not** throw). Legacy message types (`IdMessage`, `SignalPostJsonDataMessage`) marked `[Obsolete]`.
 - **`IAcSignalRHubBase.cs`** — Base hub interface: `OnReceiveMessage(int messageTag, int? requestId, SignalParams signalParams, object data)`.
 - **`ISignalParams.cs`** — `ISignalParams` base interface + `SignalParams` (Status, DataSerializerType, Parameters `byte[]?`, SignalDataType `string?`, IsRawBytesData `bool`). Metadata travels as separate hub argument (AcBinary serialized). Parameters and data are independent — both nullable in any direction.
