Update release notes with stateless mode fix (#65)

* Enable stateless mode for MCP HTTP transport

Configure the MCP server to use stateless mode by setting
options.Stateless = true in WithHttpTransport(). This eliminates
session management issues that cause "Session not found" errors
when the server restarts or clients reconnect.

Benefits:
- No session IDs required - each request is independent
- No Data Protection key management needed
- Survives server restarts without breaking client connections
- Works across multiple server instances without session affinity

Trade-off: McpServer.ClientInfo will be null as client metadata
is not tracked across requests in stateless mode.

Resolves connection issues with MCP clients including Claude Code.

* Update release notes with stateless mode fix

Add PR #64 (Enable stateless mode for MCP HTTP transport) to
the 1.7.1 release notes under Bug Fixes section. This fix
resolves "Session not found" errors experienced by MCP clients
when reconnecting or after server restarts.

Updates both RELEASE_NOTES.md and Directory.Build.props with
the new bug fix entry.
