`/delegate` without committing and pushing local changes

### Describe the feature or problem you'd like to solve

I would like to have an option to delegate tasks without committing and pushing local changes.

### Proposed solution

Let's introduce `uncommited` subcommand of `/delegate` command to delegate the task without committing and pushing local changes.

### Example prompts or workflows

`/delegate uncommited do the plan`
`/delegate uncommited complete the API integration tests and fix any failing edge cases`
`/delegate uncommited complete fix failed tests`

or just add "No, proceed" menu item here:

### Additional context

It's annoying that `/delegate` requires to do something with uncommited local changes ( commit and push or stash them) just to be able to delegate the task
Could you please make the command to be able to proceed without it?

Comienza siguiendo el comando /delegate y el menú mostrado en el issue; después, inspecciona cómo se gestionan actualmente los cambios locales antes de la delegación. Compara los workflows `uncommited` propuestos con el comportamiento existente del comando. Se considera terminado cuando la delegación puede continuar sin hacer commit, push ni stash de los cambios locales, y el workflow afectado está cubierto por tests si existen.
