Bump Python package versions for 1.7.0 release (#6142)

Bumps the released 1.6.0 packages agent-framework, agent-framework-core, agent-framework-foundry, and agent-framework-openai to 1.7.0, with root continuing to exactly pin agent-framework-core[all]. Bumps the changed prerelease packages agent-framework-a2a, agent-framework-chatkit, agent-framework-declarative, agent-framework-devui, and agent-framework-foundry-hosting to the 260528 date stamp, raises core floors on the packages included in this release, raises Foundry's OpenAI floor alongside OpenAI, and raises ChatKit's openai-chatkit floor to the minimum version required by the current typed API usage. No beta cohort bump was applied; the absent mistal/mistral package was intentionally not bumped because no such package exists in this branch.

+# MCP-Based Agent Skills Sample
+
+This sample demonstrates how to discover **Agent Skills served over MCP** with a `ChatClientAgent`.
+
+## What it demonstrates
+
+- Hosting a small MCP server (in this same executable, launched with `--server`) that
+  exposes skill resources following the SEP-2640 convention.
+- Connecting an `McpClient` to the embedded server via stdio transport.
+- Building an `AgentSkillsProvider` via `UseMcpSkills(client)`, which reads
+  `skill://index.json` (SEP-2640 canonical discovery) and constructs skills from the
+  index entries.
+- The progressive disclosure pattern across MCP: advertise → load → read resources, exactly
+  as for filesystem-backed skills.
+
+## Running the Sample
+
+### Prerequisites
+
+- .NET 10.0 SDK
+- Azure OpenAI endpoint with a deployed model
+
+### Setup
+
+```powershell
+$env:AZURE_OPENAI_ENDPOINT="https://your-endpoint.openai.azure.com/"
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-5.4-mini"
+```
+
+### Run
+
+```powershell
