chore: set native issue types in the issue forms - #23

3 findings — 3 inline, 0 deferred, 0 out of scope.

Re-verified the P1 finding after an active search for disconfirming evidence: GitHub's "Common validation errors when creating issue forms" doc confirms unexpected top-level keys cause a form validation error ("can be fixed by removing the unexpected keys"), and the issue-form syntax doc still lists only name/description/title/labels/assignees/projects/body as valid top-level keys — no type. So the added type: Task|Epic|Story key in each of the three templates is invalid and makes them unusable. All three P1 findings stand.
