Source type is now inferred from the primary key:
github_repo = owner/repo (was source=github + owner + repo)
git_url = https://... (was source=gittag + url)
gitea_repo = owner/repo (was source=gitea + owner + repo)
hashicorp_product = name (was source=hashicorp + product)
One-off dist sources (nodedist, zigdist, etc.) keep the explicit
source= key since they're already one-liners.
Parser still accepts the old format via the default fallback branch.
Updated install.sh for bat, fd, gh, goreleaser, lsd, rg, sd, watchexec,
and zoxide to extract and install shell completions (bash, fish, zsh) and
man pages from their release archives. Completions go to standard XDG
locations under the versioned opt directory. All moves use 2>/dev/null
fallbacks for older versions that don't include completions.
Declarative key=value config files that specify the release source
(github or nodedist), owner/repo, and optional tag_prefix for
monorepo packages. These replace the per-package releases.js logic
for the Go rewrite.
