Expand description
Capability noun — resolve and enable capability surfaces
(ggen capability <verb>).
A capability (e.g. mcp, web, devops) expands to a set of atomic packs.
enable records those packs in the project lockfile so a subsequent
ggen sync can generate from them; list and inspect are read-only
discovery. This is the capability-oriented entry to the same lockfile the
packs noun manages, and a natural first step for an agent bringing a project
up: pick a capability, enable it, then sync.
