atward is going to be a new TVL service, living at atward.tvl.fyi,
which users can configure as a search engine in their browser.
It will understand a variety of TVL-specific query types (such as
bug/CL links or code paths). In the future it might also support
features like go-links.
This commit configures the initial setup for query matchers in atward
and adds an example query type (for bugs).
This is not yet wired up to a web server.
