docs(installer): shorten module descriptions in the picker

The hint beside a highlighted module ran long enough to wrap, which made
the list harder to scan than the module names alone. Each description is
now a single short phrase:

- bmm  Agile AI driven development
- bmb  Skill, workflow, and agent builder
- cis  Brainstorming, ideation, and creative problem solving
- tea  Enterprise testing BMM add-on
- loop Builds, verifies, and retros a whole epic unattended
- gds  Ideate, design, and build games in any framework

TEA is the only module that depends on BMM, and its description now says
so. The others no longer imply it. "Loop" means nothing to a new user, so
that description leads with what the module does rather than its name,
and gds no longer enumerates engines.
