CallToolParams.Arguments is any.
Clients can send whatever they want.
Tool authors who create their own ToolHandler (bypassing NewTool)
will receive the arguments as a map[string]any which has been
validated against the input schema.
Tool authors who call NewTool can choose the type that the arguments
unmarshal into.
There is no double-unmarshaling and no downcasting.
There is no way for tool authors to avoid the unmarshal, and no way to
avoid the validation unless the omit an input schema, which is probably
bad for LLMs. If tool authors want this optimization, we can provide
it later.

Provide support for resource templates on the client and server.
Adding, removing and listing resource templates looks just like those
operations on resources.
Although the spec provides no guidance on the unique ID for resource
templates, we follow most existing SDKs, as well as the parallel with
resources, and index on the URI template rather than the name.
As the spec recommends, the server verifies an incoming URI in a
ReadResource request against its list of resources and resource
templates, to make sure the URI came from one of them. The main
technical challenge here is the need to check that a URI template could
have produced a particular URI.
I wrote a very simplified version of this check. At some point
we should switch to github.com/yosida95/uritemplate/v3.

Unexport our nice root-respecting local-filesystem resource handler.
It's unclear how roots should interact with a resource handler that
uses the local filesystem. All we know from the spec is that servers
should "respect root boundaries during operations," but it's not
clear how they can do that reliably if root changes are notifications,
meaning there is no causality between a client changing a root and then
asking the server for a file. (Maybe the server sees the new roots,
maybe it doesn't.)
The spec is loose about all this: it feels more like a sketch. No other
SDK seems to devote much to providing a local helper, and those that do
(Python) don't look at roots.

Make Tool APIs future-proof by pushing generics into CallToolParams, and
using CallToolParams throughout. This has several advantages:
- We no longer need the awkward CallToolOptions type, which is almost
but not quite like CallToolParams.
- NewTool no longer needs to define its own handler type: it accepts a
ToolHandler[TArgs]. This also means its signature is future-proof.
Additionally, provide a `CallTool` helper (the analog of NewTool) to
serve as a more strongly typed variant of `ClientSession.CallTool`.

JSON-level compatibility of SDK messages, and fix some bugs in our JSON
message handling:
- "params" can be missing
- "_meta" should not be null
- lists of tools/prompts/resources should not be null
In order to implement this, we need to be able to know when the server
is done processing messages. In general, this is a hard problem; for
gopls we do this with a complicated system of progress reporting and
accounting. However, the new synctest package makes this trivial, as we
can call synctest.Wait to detect when the server is idle. Therefore,
this test requires 1.25 (it uses synctest.Test, added in 1.25, and so
can't run at 1.24 with GOEXPERIMENT=synctest).

Implement the dispatcher middleware framework, allowing users to
wrap method dispatching with their own code.
The Dispatcher functions have an untyped params arg, but expect its
value to be a typed, unmarshaled XXXParams struct. That required
splitting the elegant dispatch[P, R] function into two parts, one
to do the unmarshaling and one to call the method. The nicest way
I could find to do that was to map from method names to a pair
of functions, one to unmarshal and one to call. We could also write
it as two switches on method name, which would require less machinery
but would duplicate the list of method names, already a tad fragile
because they are literal strings.
I also exported the initialize params and result, so user Dispatchers
could access them. All Params and Result types will have to be exported
for that reason.
