peptiderepo 2fcef7a323 PR Vision v0.2.0: admin/settings interface + correctness fixes (#3)
Model manager (UI-swappable models) + versioned/idempotent prv_models migration; metric comparability (config-version stamping); run-lock; projected cost + truncation state; per-model run-health; cadence reschedule; API-key 3-state; design/a11y fixes (dark v2).
