refactor(ipc): declare the SignalR wire DTOs once in ClaudeDo.Data

WorkerHub and IWorkerClient each carried their own copy of every record and
had already drifted — MergePreviewDto lost its verify fields on the client
side, two records disagreed on their name. They now live in Data/Wire.cs and
reach both sides via a <Using> item, so a hub signature change is a compile
error instead of a silently dropped JSON field.

 ## Services
 
-- **WorkerClient / IWorkerClient** — SignalR client on `http://127.0.0.1:47821/hub`, auto-reconnect with exponential backoff. The surface **tracks `WorkerHub`** — treat `src/ClaudeDo.Worker/Hub/WorkerHub.cs` as the canonical method list rather than duplicating it here. Events mirror `HubBroadcaster`. Lifecycle (`StartAsync`/`StopAsync`) and a few admin methods live only on the concrete `WorkerClient`.

The wire DTOs are **not** declared here: they live once in `ClaudeDo.Data/Wire.cs` and reach both sides via a `<Using Include="ClaudeDo.Data.Wire" />` item in the csproj (Ui, Worker, and both test projects), so a hub signature change is a compile error instead of a silently dropped JSON field. Add new ones there, never a local copy. Events mirror `HubBroadcaster`. Lifecycle (`StartAsync`/`StopAsync`) and a few admin methods live only on the concrete `WorkerClient`.
 - **INotesApi / WorkerNotesApi** — daily-note CRUD; UI DTO `DailyNoteDto(Id, Date, Text, SortOrder)`.
 - **IPrimeScheduleApi** — prime-schedule CRUD.
 - **UpdateCheckService** — polls releases; `LastCheckStatus`/`LatestVersion`/`CheckNowAsync` feed the shell's update banner.
