fix: exclude smoke-*.ts from typecheck (they import from dist/)

scripts/smoke-deno.ts and scripts/smoke-worker.ts validate the *built*
artifacts, so they import from ../dist/*.js. The Typecheck CI job runs
without first building, which made tsc fail to resolve those imports.
Their own CI jobs (Smoke Deno, Smoke Workers) run after a build, so the
exclusion doesn't reduce coverage — it just stops Typecheck from
needing a build step that's irrelevant to it.
