* fix: always include files from the same workspace as the build target in `copy_to_directory`
Fixes #359.
This updates the `copy_to_directory` tool to accept a workspace name representing the workspace of the target it is executing under. Any files in this workspace are automatically included, regardless of the `include_external_repositories` option. This makes it support usage within an external target (such as `@wksp//:dir`).
* test: add e2e test which uses `copy_to_directory` within an external workspace
Refs #359.
This should catch regressions where no files are copied when built within an external workspace and not using `include_external_repositories`.
* ci: fix stray workspace refs
