A `default-packages` file saved with Windows line endings left a carriage return on every package name,
and turned each blank line into a lone `\r` entry, so `npm install -g` was given `rimraf\r` and failed.
Strip a trailing `\r` from each line before parsing it,
like `.nvmrc` parsing already tolerates.

nvm.sh uses `NVM_SCRIPT_SOURCE="$_"` to detect its source location.
Adding `: nvm.sh` before each source line ensures `$_` is set correctly, preventing breakage when the previous command (e.g., `set -ex`) overwrites it.
