bb2347385e internal/mcp: add iterator methods resources and prompts
This CL streamlines the client side pagination logic by adding a generic
helper that handles pagination. This also simplifies the existing tools
iterator method.

8962b38ba5 internal/mcp: add pagination for tools
This CL adds paginating functionality for tools. It uses the gob encoder
for creating opaque cursors. More CLs to follow for paginating other features.

a8b98da480 internal/mcp: reinstate ClientSession
Add a logical client session type back to the SDK, to bring it closer to
the design. Also, remove 'ConnectionOptions', which is better
implemented using middleware, and reimplement logging as a
LoggingTransport middleware, which is also added to the design.

dbf57af24b internal/mcp: rename LocalTransport->InMemoryTransport, and document
Update the design to mention our in-memory transport, since it is
generally useful, and update the implementation to use distinct types
for InMemoryTransport and StdIOTransport (the fact that they are both
implemented as an io.ReadWriteCloser is an implementation detail).

ServerConnection to ServerSession. Also update variable names, which
were in various states of disarray from the multiple renamings of this
type.

347a1a0078 internal/mcp: rename ClientConnection to ServerConnection
It's too confusing that you send server requests through the Client, and
send client requests through the ClientConnection. Rename
ClientConnection to ServerConnection, so that the types on the
server side of the control diagram start with 'Server'.
