fix(test): keep vitest default excludes

[dreyfus92]

the shared vitest config sets exclude: ['dist/**', 'node_modules/**'], which replaces vitest's defaults instead of extending them. node_modules/** only matches the root one, so in a pnpm workspace run from the root vitest follows the workspace symlinks into nested node_modules and runs the same tests again. now it spreads configDefaults.exclude and keeps dist/**.

added a test that runs bsh test against a workspace with a symlinked package and checks only the real test file gets collected, it fails on main without the fix.
