[Feature Request] Plugin name not searchable in slash command auto-complete

Bug Description
We are making lots of organization skills and commands. We've put them in claude marketplaces and plugins. The plugin that provides the skill and command shows up parenthetically in the slash command description; however, the plugin name is not used in slash command auto-complete. This makes it very hard to find all of the commands and skills provided by a plugin. For example, this is the plugin metadata page for our 'ai-sdlc' plugin:

<img width="1572" height="247" alt="Image" src="https://github.com/user-attachments/assets/3239a444-c439-4020-a7b9-3f23455e05dc" />

However, typing /ai-sdlc only reveals 1 skill to autocomplete

<img width="596" height="184" alt="Image" src="https://github.com/user-attachments/assets/f97ba608-e3e1-418a-bef2-788cb9dd4974" />

There's no way to search for all the "ai-sldc" provided skills. The only workaround is prefixing everything, but that takes up extra context and seems kludgy. I _think_ commands still add a prefix, but we don't want to convert our skills to commands.

Can you please make plugin name searchable in the forward slash autocomplete?
