Derive the native Codex ladder from canonical provider metadata. The fallback hardcodes provider capability metadata outside the registry and derivation flow. If the canonical ladder changes, this exporter can advertise stale levels. Define the native ladder in the canonical provider metadata and derive model.reasoningEfforts from it before exporting.

In `@src/clients/config-export.ts` at line 1108, Move the native Codex reasoning
ladder from the fallback in the config export flow into the canonical provider
metadata, then derive model.reasoningEfforts from that metadata before
exporting. Update the relevant provider metadata and export derivation symbols,
preserving the existing level order and fallback behavior where applicable.

Add a negative Gajae export test for excluded-only effort ladders. The existing test detects a regression that leaves ultra in a mixed ladder. It does not detect metadata emitted when reasoningEfforts contains only none and ultra.

Add a model with reasoningEfforts: ["none", "ultra"] and assert that its exported entry has no reasoning, thinking, or compat fields. The expected output is a model without reasoning metadata because filtering removes every declared effort.
