feat: add typecheck and test commands for examples submodule

Add typecheck support to examples:
- Add vitest typecheck configuration to examples/vitest.config.ts
- Add typecheck script to examples/package.json

Add aggregate commands in root package.json:
- test:examples - Run tests in examples submodule
- test:all - Run all test:* scripts using pattern matching
- typecheck:examples - Run typecheck in examples submodule
- typecheck:all - Run all typecheck:* scripts using pattern matching

This allows running tests and typechecks across all submodules with
a single command using pnpm's regex pattern matching.
