refactor: update router import path and add random ID utility

- Changed the import path for router types from '@kevisual/router' to './route.ts' in src/router-define.ts.
- Added a new lock file (bun.lock) to manage dependencies.
- Introduced a new utility function in src/utils/random.ts to generate random IDs using the nanoid library.
