feat(worker): map MCP HTTP endpoint and broadcast TaskUpdated

Browse Source 
- Add PlanningMcpContextAccessor (Option A) to read PlanningMcpContext
  from HttpContext.Items set by PlanningTokenAuthMiddleware
- Annotate PlanningMcpService with [McpServerToolType]/[McpServerTool]
  and remove PlanningMcpContext ctx parameter from all tool methods
- Broadcast TaskUpdated(parentTaskId) via HubBroadcaster after every
  mutation in PlanningMcpService
- Refactor PlanningSessionManager to accept IDbContextFactory for
  singleton-safe use in DI; keep direct-repo ctor for tests
- Register PlanningSessionManager (singleton), IPlanningTerminalLauncher,
  PlanningMcpContextAccessor, PlanningMcpService, and MCP server in
  Program.cs; wire PlanningTokenAuthMiddleware and MapMcp("/mcp")
- Update PlanningMcpServiceTests with fake HttpContext accessor and
  no-op HubBroadcaster (avoids Moq dependency)
