## What changed
Removed stale `tests-ui` configuration and documentation references from
the repo.
## Why
`tests-ui/` no longer exists, but the repo still carried:
- a dead `@tests-ui/*` tsconfig path
- stale `tests-ui/**/*` include
- a Vite watch ignore for a missing directory
- documentation examples that still referenced the old path
## Validation
- `pnpm format:check`
- `pnpm typecheck`
