Module proxy 

Per-ecosystem proxy-config emit per [per-ecosystem-proxy-config-emit-format decision 2026-05-20]. Phase 1 Tier A: npm + pypi + go.

CLEANLIB-373 + CLEANLIB-374 (cycle-18): extend the accepted-ecosystem list with crates (cargo) and maven. The 8-ecosystem catalog the wire supports today (npm, pypi, go, crates, maven, nuget, rubygems, composer) was already locked in cli_matrix fixtures + the ecosystem-specific crates (cleanlib-ecosystem-*); config init was still refusing two of the eight at the CLI validation layer despite the App backend accepting them.

Each emit function returns a ProxyConfig holding the config-blob text + the canonical local path where the file would be written. Callers (typically [cleanlib config init]) decide whether to write or print.

ProxyConfig

Emitted config: blob is the literal file/shell content; canonical_location is the default write path (or empty for ecosystems without a single canonical file like Go’s GOPROXY env).

Enums

Ecosystem

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