feat(web/atward): Implement match scaffolding for TVL redirector r/2559

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.
