fix(auto-update-checker): add bun.lock handling to invalidatePackage()

- Removes package from node_modules, package.json dependencies, AND bun.lock (workspaces.dependencies + packages)
- Fixes issue where 'update available' notification appeared but actual update didn't happen on restart due to bun.lock pinning old version
- Added BunLockfile interface and stripTrailingCommas helper for JSON parsing
