Spec drift detected

Upstream specs changed since the last sync. This workflow runs with
contents: read only — it does NOT push a branch or open a PR.

To resolve: locally run uv run python scripts/sync_spec.py +
uv run python scripts/generate.py, audit the diff (including
kalshi/_generated/models.py), and open a PR whose body contains
Closes #<this issue number> so this issue auto-closes on merge.
