Enum Ecosystem 

pub enum Ecosystem {
    Npm,
    Pypi,
    Go,
    Crates,
    Maven,
    Nuget,
}

Locked vocabulary per matrix §8 — ecosystem identifiers are always lowercase.

CLEANLIB-373 + CLEANLIB-374 close: Crates and Maven join the accepted set. Both emit shell-snippet form (no canonical_location) because the canonical config file placement is workflow-dependent — cargo per-user (~/.cargo/config.toml) vs per-workspace, maven per-user (~/.m2/settings.xml) vs per-project mvn -s. config init prints the snippet + the recommended file path in the header line rather than silently mutating either default. Sister of the Ecosystem::Go shape which follows the same shell-snippet pattern for GOPROXY / GOAUTH.

CLEANLIB-818 close: Nuget joins the accepted set. All four App-side layers nuget requires were verified live in prod (service index + list_versions enumeration + attested .nupkg serve + a provisioned drain job) — the refusal here had no technical basis, a stale hard-coded allow-list. Rubygems and Composer deliberately do NOT join: per CLEANLIB-818’s own explicit scoping, the platform genuinely does not resolve those two yet (their App-side endpoints 404) — adding them to this enum would silence a CORRECT refusal and hand a customer a config that looks right and fails on every restore. That work is server-side, tracked in CLEANLIB-818’s sibling ticket, a different repo. Nuget follows the Maven precedent (XML merged into an existing file, not npm’s, since NuGet.Config is XML with the same mirror-entry + credential-block shape) and the same canonical_location- empty reasoning: NuGet.Config resolution is per-project or per-user (~/.nuget/NuGet/NuGet.Config / %APPDATA%\NuGet\NuGet.Config), workflow-dependent same as cargo/maven.
