Streaks and Breaks

### Brief description
As a _User_
I need _to track my habit streaks and any breaks I take_
So that _I can stay motivated by seeing my progress and understand when I fall off track_


### Details and Assumptions
* Streaks represent consecutive days of successful habit completion.
* Breaks represent days where the user fails to complete a habit.

### Acceptance Criteria

```gherkin
Given I have completed a habit for consecutive days
When I view my streaks
Then I should see the number of days I’ve kept the streak
```

```gherkin
Given I fail to complete a habit for a day
When I view my breaks
Then the streak should reset and the break should be recorded
```
