chore(github): add issue templates (bug / feature / question)

YAML issue forms with required fields so new reports arrive with the
context needed to act on them (version, OS, reproduction steps for
bugs; problem-before-solution for features). Auto-applies the matching
label.

blank_issues_enabled: false forces use of one of the three templates.
config.yml also surfaces the Patreon link as a contact option.
