Current topic: "Refining Email Validation"
Topic summary: I am updating the email validation logic in `ReportBugViewModel.kt` to address the leniency of the default Android email pattern. Specifically, I'm ensuring that any provided email address contains at least one dot in the domain part. This aligns with the reviewer's feedback and helps prevent invalid submissions. I will also be updating the relevant tests to verify this new behavior.

Strategic Intent: Refining email validation in `ReportBugViewModel.kt` to be stricter.
