CommandProviderInterface

Declares that a plugin contributes commands to the kernel's command table — the discovery seam for Command-as-atom's CLI surface (see `docs/library/vision-milpa-commands.md`). This is the command counterpart of {@see \Milpa\Runtime\Http\RouteProviderInterface}: {@see Kernel::boot()} checks every successfully booted plugin for this interface and merges its {@see commands()} into the {@see Kernel::commands()} list it exposes — the same "instanceof, then auto-wire" pattern the family already uses for routes and tools, applied to the new {@see CommandDefinition} atom. A host CLI (e.g. `milpa/framework`'s `coa`) registers every discovered command as a subcommand instead of hardcoding them, and a plugin can therefore add its own `coa` command with zero host-file edits.
