Validate tool annotations value
...
Tool annotations were introduced in the "2025-03-26" specification:
> Added comprehensive tool annotations for better describing tool behavior,
> like whether it is read-only or destructive (PR modelcontextprotocol/modelcontextprotocol#185 )
https://modelcontextprotocol.io/specification/2025-03-26/changelog#major-changes
This means they are not supported in the "2024-11-05" specification,
so validation errors will be raised for `protocol_version: "2024-11-05"`.

Fix errors when title is not specified
...
Since the optional `title` becomes `title: null` when not provided, the following error occurs.
This occurs with Claude Code 1.0.100.
```console
[DEBUG] MCP server "example": Connection failed after 1591ms: [
{
"code": "invalid_type",
"expected": "string",
"received": "null",
"path": [
"serverInfo",
"title"
],
"message": "Expected string, received null"
}
]
```
By adding `compact`, the `title` key will be removed if the optional `title` keyword argument is not specified.

Add title to serverInfo
...
Follow-up to #109 .
`title` has also been added to `serverInfo` and `clientInfo` by
https://github.com/modelcontextprotocol/modelcontextprotocol/pull/663 .
Since `clientInfo` is not treated as product code, support is implemented only in `serverInfo`.
See also https://modelcontextprotocol.io/specification/2025-06-18/schema#implementation .

Add instructions support to MCP::Server
...
The response of the `init` method can include `instructions`.
https://modelcontextprotocol.io/specification/2025-06-18/basic/lifecycle
`instructions` appear to be supported starting from the 2025-03-26 specification.
- https://modelcontextprotocol.io/specification/2025-03-26/basic/lifecycle (supports `instructions`)
- https://modelcontextprotocol.io/specification/2024-11-05/basic/lifecycle (does not support `instructions`)
If `instructions` is used with an unsupported protocol version, an `ArgumentError` will be raised.
As additional context, the TypeScript SDK also treats `instructions` as optional.

Remove duplicate method instrumentation

`handle_request` already adds the `method` to the instrumentation data,
so there is no need to repeat this. Moreover, consumers can override
these anyway.

Refactor MCP tool and server to handle optional server_context parameter
...
- Updated `call` method in `MCP::Tool` and `MCP::Prompt` to accept `server_context` as an optional parameter.
- Refactored `MCP::Server` to streamline argument handling for tool and prompt calls, introducing helper methods `call_tool_with_args` and `call_prompt_template_with_args`.
- Adjusted tests to reflect changes in method signatures and ensure compatibility with optional `server_context` parameter.
