fix(compiler): add apps directory to compiler workspaces

The 'start' and 'next' scripts reference 'yarn workspace playground'
but the playground app in apps/playground was not included in the
workspaces configuration. This caused these commands to fail.

Added 'apps/*' to the workspaces.packages array to properly register
the playground workspace.
