🚀 Features

• Use the Streamable HTTP transport for MCP - @pubmodmatt PR #2607

  rover dev --mcp will now use the Streamable HTTP transport instead of SSE. Specify the --mcp-port and/or --mcp-address options to rover dev --mcp to override the default values. The --mcp-sse-port and --mcp-sse-address options still work, but will configure the port and address for Streamable HTTP. Users should migrate to the new option names.
