Subject: [PATCH] fix(typecheck): regenerate route types and skip stale dev
 validator

`npm run typecheck` failed with 8 TS2307 errors from Next's generated
route validators referencing old page paths (e.g. calendar/page.js) after
routes moved to catch-all segments. Two causes:

- The production validator (.next/types) was stale. Prepend `next typegen`
  so `tsc` always runs against freshly generated route types.
- The dev validator (.next/dev/types) is a turbopack-dev-only artifact that
  is absent from clean/CI checkouts and goes stale locally. `next typegen`
  force-re-adds it to tsconfig `include`, so exclude it instead (exclude
  overrides include), leaving route typing to the maintained .next/types.

tsc still catches real type errors; verified `npm run typecheck` is clean
and idempotent.
