File	Description
package.json	Updated typescript-eslint dependency from 8.48.1 to 8.49.0
yarn.lock	Updated lockfile entries for typescript-eslint (all @typescript-eslint/* packages), baseline-browser-mapping, expect-type, fast-copy, type-fest, and vite; removed graphemer package (no longer a dependency of typescript-eslint 8.49.0)
.yarnrc.yml	Added @willbooster/shared-lib to npmPreapprovedPackages list

All dependency updates appear consistent and properly synchronized. The removal of the graphemer package is expected as it's no longer a dependency in typescript-eslint 8.49.0. No issues were identified in this PR.
