Stacked on the modifications PR. Now that no live code path references
the per-package fetchers, the shared HTTP/parsing helpers, the
in-process normalizer, or the example template, delete them. Pure
deletion — no behavior change.
- ~93 per-package <pkg>/releases.js fetcher modules.
- _common/{brew,fetcher,git-tag,gitea,github,github-source,
githubish,githubish-source}.js shared HTTP/parsing helpers.
- _webi/normalize.js in-process normalization layer (cache files
arrive normalized from webicached).
- _example/releases.js fetcher template for new packages.
The Go cache daemon (webicached) is now the sole producer of release
metadata; the Node process never makes an upstream request.

How transform or zip an array
Anything that doesn't start with a . is part of the transformation template.
Anything that collects starts with .[].
Anything that transforms has a pipe and selector | .whatever.
