This PR fixes incorrect capabilities handling for `completion/complete`.
As specified, the capability of `completion/complete` is `completions`, not `prompts`:
https://modelcontextprotocol.io/specification/2025-03-26/server/utilities/completion#capabilities
Note that in the Ruby SDK, `completion/complete`, like `logging/setLevel`, is not yet implemented.
Therefore, an empty implementation has been added to server.rb.
RubyGems may be used across a wide range of Ruby versions,
from the minimum supported version to development versions.
To allow local development with any Ruby version,
the Ruby version is not locked using a `.ruby-version` file.
This enables developers to work with their preferred Ruby version and
frees repository maintainers from the need to update `.ruby-version`.
Additionally, because testing against supported Ruby versions is performed
in CI before release, the version in `.ruby-version` is not important.
If there are many searches in the `$LOAD_PATH` in the user environment,
require will perform unnecessary searches that are not needed.
In contrast, `require_relative` is efficient because it uses a relative path.
JSON-RPC is handled by https://github.com/Shopify/json-rpc-handler,
so `ModelContextProtocol::JsonRPC` module seems to have been
unintentionally left behind in the following commit:
c5591be
The files under `model_context_protocol/json_rpc/*.rb` have already been removed.
- add support for resource templates
