Extension methods for mapping Novior.MentorAgent.Server endpoints.

## Definition

Namespace: `Novior.MentorAgent.Server.Extensions`. Package: `Novior.MentorAgent.Server`.

`public static class ServerEndpointExtensions`

```shell
dotnet add package Novior.MentorAgent.Server
```

## Methods

### `MapMentorAgentServer`

`public static IEndpointRouteBuilder MapMentorAgentServer(this IEndpointRouteBuilder endpoints, string hubPath = "/mentor-hub", string ssePath = "/mentor/chat", Action<IEndpointConventionBuilder>? configureTransports = null)`

Maps all Novior.MentorAgent.Server endpoints:

- `/mentor-hub` — SignalR hub (Blazor WASM, MAUI, console .NET)
- `GET /mentor/chat` — SSE streaming (React, Vue, fetch API, curl)
- `POST /mentor/chat` — SSE streaming with image attachments (roadmap \#13)
- `POST /mentor/approve` — human-in-the-loop approve/deny (roadmap \#16)
- `POST /mentor/cancel` — stop the in-flight turn of a SignalR connection
- `GET /mentor/session` and `POST /mentor/session` — save and restore the conversation of a SignalR connection, as a protected snapshot bound to its owner
- `GET /mentor/admin/metrics` — token &amp; cost snapshot, role-gated (roadmap \#9)
- `GET /mentor/tour` — onboarding tour steps (roadmap \#18)

MCP and A2A endpoints are mapped separately via `MapMentorAgentMcp()` and `MapMentorAgentA2A()`, also in this package.

```text title="Example"
app.MapMentorAgentServer();          // SignalR + SSE
app.MapMentorAgentMcp();             // optional MCP server
app.MapMentorAgentA2A();             // optional A2A agent
```

**Parameters**

- `hubPath`: SignalR hub path. Default: /mentor-hub
- `ssePath`: SSE endpoint path. Default: /mentor/chat
- `configureTransports`: Applied to the hub and both SSE endpoints — the three that **run a turn**. This is where a host requires authentication on them: `app.MapMentorAgentServer(configureTransports: e => e.RequireAuthorization());` Optional, and omitting it changes nothing (BUG-060). But the default is worth understanding before leaving it: `POST /mentor/chat` runs a paid turn for an anonymous caller. With `AnonymousIdentity = Shared` every anonymous caller has the memory key `"anonymous"`, so one user's remembered facts are injected into another's turns — fine for a single-user demo, a cross-user leak for anything else. With `PerSession`, the default, nothing is shared, but each request or connection is a new key: neither memory nor `RateLimitPerUser` follows a person.
- `endpoints`: The application's endpoint route builder.
