Module handler 

Generic handler transport for staged command migration.

The output type is generic so FEAT-014 does not move or duplicate the TUI-owned CommandResult. During in-place adoption, the TUI instantiates CommandHandler<crate::commands::CommandResult>.

Structs

CommandContexts

Transport envelope with one independently optional facet slot.

ContextParts

Consumed envelope used when one handler needs several independent facets.

Enums

CommandHandler

A command handler that is either argument-only or capability-scoped.
