chore(github): add Feature Request issue template

Previously only Bug Report existed (and blank issues are disabled), so feature
requests had no structured form. Mirrors bug_report.yml style; labels new issues
'feature request' to match the repo label taxonomy; includes an Area dropdown
(plugin / Pi / dashboard / CLI / memory).
