Phase 2 amendment for #2753 (Drew, 2026-10-30: "should use contributor and disable all other muse meta providers and replace with this") — the proxy half. The config half (contributor models in muse-direct, other Meta doors disabled, route retargets) follows in a separate PR.

What

resolveModelAndEffort in bin/muse-proxy.mjs now understands contributor ids:

• muse-spark-1.3-contributor / muse-wonder-1.0-contributor resolve to their base model for lookup, then the resolved baseModel re-attaches -contributor, so direct mode sends the contributor id upstream on /v1/responses verbatim.
• An effort suffix after the contributor part parses as the effort: muse-wonder-1.0-contributor-high → base muse-wonder-1.0-contributor, effort high, fullName muse-wonder-1.0-contributor-high.
• A plain base-model request still sends the plain id — contributor is the caller's (config's) choice, never a proxy rewrite.

Test

New unit test (stub Meta API): contributor + effort-suffix parse, contributor with default effort, and the plain-id no-rewrite guard, asserting the exact upstream model/reasoning bodies. Full file on the laptop: 20/20 pass (19 prior + this one).
