fix(ci): remove examples folder that broke pnpm lockfile

The examples/ folder had its own package.json files which pnpm detected
as workspace projects, causing CI to fail with frozen-lockfile error.

Removed examples for now - can be added later as a separate repo or
with proper workspace exclusion.
