//! `workspace/executeCommand` dispatcher.
|

|
|
//!
|
|||
|
|
//! Phase 13 lands the router + the first command. Phases 14–17 register
|
|||
|
|
//! their own commands here. Each handler returns the `WorkspaceEdit` it
|
|||
|
|
//! wants applied; the `Backend` calls `client.apply_edit` after the call.
|

|

//!
|
|||
|
|
//! Phase 13 surface:
|
|||
|
|
//! - `nuwiki.file.delete` — args: `{ "uri": <Url> }`
