* fix(core): add IF NOT EXISTS to migration 033 index creation
The schema registry's createContentTable() creates composite indexes
on content tables at creation time. When migration 033 runs on a
database where tables were created after the registry added these
indexes, it fails with "index already exists". Adding IF NOT EXISTS
makes the migration idempotent.
* refactor(smoke): trim site matrix to templates + playground, remove typechecks
The smoke test matrix included every demo and template, plus typecheck
cases. This was slow and redundant — typechecks are already covered by
pnpm typecheck, and demos are dev targets not release artifacts.
Trim to templates + playground only, and replace the sequential per-site
astro build with a single recursive pnpm build. Remove the TypecheckSiteCase
type and handling since smoke tests should only verify runtime behavior.
* Update env
* chore: add changeset for migration 033 fix
