Upstream uses non-standard OS/arch names (x64, ia32, win32, arm) and
ships both bare binaries and .gz-compressed copies. classifyFFmpegDist
maps those to canonical names and keeps only bare binaries.
Also adds source-override logic to installerconf so that
github_releases + source = ffmpegdist works: GitHub is used for
fetching while the custom classifier handles classification.
Rewrites the Node.js release classification pipeline in Go. webicached
fetches upstream releases (GitHub, Gitea, GitLab, HashiCorp, custom
sources), classifies assets by OS/arch/variant, and writes legacy-format
JSON caches compatible with the existing webinstall.dev API.
Git-clone packages emit git_tag and git_commit_hash from real repo
clones — no fabricated refs.
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.
