Add issue templates for bugs and features

[RaymondAbiola]

Summary

Issues here follow a consistent shape because they are written by the maintainer. Outside reporters have no such guide, so templates keep incoming issues actionable.

Acceptance criteria

• Templates exist for a bug report and a feature request.
• Each asks for the information needed to act on the issue.
• They appear in the issue creation chooser.
