UX: Generator output shows misleading paths for generated files #28

Current Behavior

When labelle generate runs, it shows output like:

Generating for target 'raylib_desktop':
  - raylib_desktop/main.zig
  - raylib_desktop/build.zig
  - raylib_desktop/build.zig.zon
Generation complete!

This suggests the files are in raylib_desktop/ relative to the project root, but they're actually in .labelle/raylib_desktop/.

Expected Behavior

The output should show the actual paths:

Generating for target 'raylib_desktop':
  - .labelle/raylib_desktop/main.zig
  - .labelle/raylib_desktop/build.zig
  - .labelle/raylib_desktop/build.zig.zon
Generation complete!

Or at minimum, indicate the base directory:

Generating for target 'raylib_desktop' in .labelle/:
  - main.zig
  - build.zig
  - build.zig.zon
Generation complete!

Impact

• New users might look for files in the wrong location
• CI scripts need to know the actual path structure
• Documentation needs to explain the .labelle/ prefix

This caused confusion during CI integration testing where we initially tried to cd to raylib_desktop/ instead of .labelle/raylib_desktop/.
