## What
`feature:enable <feature> <target>` now accepts a percentage like `25%`
as the target, in addition to a user email or `all`.
```bash
php artisan feature:enable AiConsentSettings 25%
```
This activates the feature for a random `ceil(total * N/100)` sample of
the **current** users, persisted in Pennant's `features` table — no need
to edit the feature class and redeploy for a percentage-based rollout.
## Notes
- It targets the current user base. New users keep the feature's default
(`false`) unless the command is run again.
- Percentage is validated to be between 1 and 100.
- `feature:disable` was left unchanged — disabling for a random subset
has no clear use case.
## Test plan
- [x] `feature:enable AiConsentSettings 40%` enables the feature for
exactly 4 of 10 users
- [x] An out-of-range percentage (`0%`) fails
