Novior.MentorAgent 1.0.0

Changed

• Breaking — all packages: the packages are now Novior.MentorAgent, Novior.MentorAgent.Abstractions,
  Novior.MentorAgent.Blazor, Novior.MentorAgent.Declarative and Novior.MentorAgent.Server; the MentorAgent.*
  ids end at 1.0.0-rc.15. The namespaces follow (using Novior.MentorAgent.Extensions;), the widget's static files
  are served from _content/Novior.MentorAgent.Abstractions/, and the log categories start with
  Novior.MentorAgent, so a "MentorAgent" filter under Logging:LogLevel no longer matches. The five packages
  depend on each other at their exact version. Unchanged: the types and extension methods (AddMentorAgent,
  MentorOptions, …), the routes, the telemetry source, meter and metric names, the session snapshot format, the
  MentorAgentMcp CORS policy, MentorAgent.css, MentorAgent.js and window.MentorAgent. The README's
  Migrating from the MentorAgent.* packages walks through the move.

Fixed

• Novior.MentorAgent: four Warnings outside the tool gate still carried a whole exception, whose text comes from the
  host's code: a UI action that threw, with a ChatClient or a pre-built Agent, and an OnToolResult or a
  McpCallerPrincipal that threw on the MCP server. As in the gate, they name the exception's type; the whole
  exception is logged at Debug (BUG-152, S3).
• Breaking — Novior.MentorAgent.Server: AddMentorAgentMcp() or AddMentorAgentA2A() called before AddMentorAgent(),
  or with McpServerEnabled / A2AServerEnabled turned on after AddMentorAgent() read them (a Configure or
  PostConfigure of MentorOptions), registered nothing and said nothing; the map call failed later, in the
  second case naming a call the host had made. The host now stops at start-up with the reason and the fix, and
  one that ran without the server because of it no longer starts (BUG-153, S3).
• Novior.MentorAgent: the README and the rc.15 notes said that the warning about writes that run without
  confirmation comes at startup. It comes the first time the actions are read: at startup only with
  WarmUpAtStartup or MapMentorAgentA2A(), otherwise with the first conversation or the first MCP or tour
  request. With [Description] alone it also names the methods that only read, until IsReadOnlyAction or
  [MentorAction(ReadOnly = true)] declares them. The README now says both (BUG-154, S3).
• Novior.MentorAgent.Server: the README's minimal SignalR client called Stop, the confirmations and the session
  save and restore without the hub's credentials: with cookies from another origin, or a bearer token, those
  calls were anonymous and did nothing. It now sends them, like the complete components. The README also no
  longer says that the MCP and A2A servers are built into MentorAgent (BUG-155, S3).
• Novior.MentorAgent: the READMEs, the XML documentation of AddMentorAgent() and the start-up warning for a
  callback that throws listed AppDescription and AgentCard among the options read at registration.
  Only AppName is, as the MCP server's name; the A2A card is built from the real options when
  MapMentorAgentA2A() runs (BUG-156, S4).
• Novior.MentorAgent: the README's MAUI step 3, pasted into the MAUI Blazor Hybrid template, did not compile: it
  lacked using System.Reflection; and using Microsoft.Extensions.Configuration;, and AddUserSecrets needs
  Microsoft.Extensions.Configuration.UserSecrets, which neither the template nor MentorAgent brings. The step
  now names both and the package, and says that AddUserSecrets needs the project's UserSecretsId and finds
  the secrets only on the development machine (BUG-157, S3).
• Novior.MentorAgent.Abstractions: its README said that the core package depends on
  ModelContextProtocol.AspNetCore; since rc.15 that transport is in the Server package, and the core
  references ModelContextProtocol (BUG-158, S3).
