fix: normalize string entries in loadComponents to prevent padEnd crash (#273)

`agentsys list` commands crash with "Cannot read properties of undefined
(reading 'padEnd')" because components.json stores entries as plain
strings while the display code expects objects with a .name property.
Normalize string entries to {name} objects when loading from JSON.
