feat(commands): add mountSubCommands for flat sub-command grafting#36
Merged
Conversation
mountSubCommands(cmd) grafts another command's sub-commands into this command tree at the same level (/root <sub>), unlike mount(cmd) which nests them under the source name (/root <cmd-name> <sub>). Lets a plugin contribute top-level sub-commands to a shared root it does not own. The source command's own bare execute is intentionally not carried over. Covered by MagicCommandCompositionTest.

@SubCommandmethods on a carrier class, flat-mount that carrier into a copy of the root, re-register. The source command's own bareexecuteis intentionally not carried over — only its sub-commands.Covered by new cases in
