Subject: [PATCH] fix(core): remove stale model resolver input

The model resolver no longer depends on the original user input after the short-first-turn fast-model strategy was removed. Remove the obsolete parameter and its call-site plumbing, and keep the external route-root helper test-only so normal builds do not report dead code.
