* .NET: Remove Foundry Toolbox server-side tools support
Mirrors the Python cleanup in microsoft/agent-framework#5671. Passing
toolbox tools as server-side Responses tools is not the experience we
want to support; the hosted-agent MCP toolbox path (HostedMcpToolboxAITool
+ FoundryToolboxService) remains the supported way to consume Foundry
Toolboxes.
Removed:
- FoundryToolbox static class (GetToolboxVersionAsync / GetToolsAsync /
ToAITools / SanitizeAndConvert)
- AIProjectClient.GetToolboxToolsAsync extension
- Agent_Step25_ToolboxServerSideTools sample (+ slnx entry)
- FoundryToolboxTests, TestDataUtil, HttpHandlerAssert, and the toolbox
JSON fixtures only those tests referenced
- ToolboxHostedAgentTests and ToolboxHostedAgentFixture; the "toolbox"
switch arm + CreateToolboxAgent helper in TestContainer; matching
README scenario row and bootstrap script entry
Kept (MCP path, unchanged):
- HostedMcpToolboxAITool, FoundryAITool.CreateHostedMcpToolbox,
FoundryAIToolExtensions.CreateHostedMcpToolbox(ToolboxRecord/Version)
- FoundryToolboxService, AddFoundryToolboxes, marker injection in
AgentFrameworkResponseHandler, InputConverter.ReadMcpToolboxMarkers
- Hosted-Toolbox sample, McpToolbox* tests, FoundryToolboxServiceTests

* .NET: Add Foundry Toolbox MCP sample (Agent_Step25_FoundryToolboxMcp)
Adds a non-hosted-agent equivalent of the Python foundry_chat_client_with_toolbox.py sample. The agent connects to a Foundry Toolbox's MCP endpoint via Streamable HTTP, injects a fresh Azure AI bearer token on every request, and discovers the toolbox's tools at runtime via McpClient.ListToolsAsync.

* .NET: Tighten Agent_Step25_FoundryToolboxMcp README/Program comments
Drop 'non-hosted agent' framing from README (this sample isn't related to hosted agents) and remove narrative comparison to server-side tools from the Program.cs header comment.

* Drop python sample reference from Agent_Step25 README

* Drop incorrect .NET 10 prereq from Agent_Step25 README
Toolboxes don't require .NET 10 (Microsoft.Agents.AI.Foundry targets net8.0+); the parent AgentsWithFoundry README already lists the sample SDK prereq.

* Fix Toolsets api-version in Agent_Step25 example endpoint
Use 2025-05-01-preview to match FoundryToolboxOptions.ApiVersion. The placeholder 'v1' is not accepted by the Toolsets endpoint.
