The two static-catalog-change invalidation tests asserted the newly-appended
opencode-go model appeared in the group's visible `models` list. That held when
the test was written (opencode-go had 14 static entries), but the curated list
has since grown to 27 — past the model-picker overflow threshold — so the
rebuilt group now splits into a visible `models` head (capped) plus an
`extra_models` overflow tail, and the appended entry (added at the end) lands in
`extra_models`. Cache invalidation itself works correctly; the assertion was
stale.
Assert the appended model is surfaced across the combined picker catalog
(`models` + `extra_models`) so the test stays a pure cache-invalidation
regression check, independent of the overflow cap. Verified non-vacuous (a
genuinely-absent id still fails). No production change.

Two existing tests asserted _load_models_cache_from_disk()/get_available_models()
return EXACTLY the saved payload; the loaders now also return aliases reconstructed
from config (empty {} when no config aliases). Update both assertions to expect the
aliases field. Caught by the full suite + Codex re-gate.
