Consider adding issue templates — the tracker is drowning in unrelated requests

Love the project, but scrolling through the open issues lately, most of them are unrelated support requests ("hack my Instagram", "recover my Google account", betting app stuff...). Real bug reports are getting buried, which hurts maintainers and anyone trying to contribute.

Checked the repo and there's no .github/ISSUE_TEMPLATE yet — only workflows/.

Would you be open to a PR that adds:

1. A bug report template with the basics that #513/#499/#444 style reports always end up needing anyway:
   • PentestGPT version / commit
   • backend used (claude / codex / local model via ccr)
   • steps to reproduce, expected vs actual
   • confirmation checkbox that the target is one they're authorized to test
2. A question template (or just a note pointing questions elsewhere) — half the current issues are questions rather than bugs
3. Optionally blank_issues_enabled: false so reports at least pick a category

The authorization checkbox especially would make it much easier to close the "hack someone's account" requests quickly — right now maintainers have to answer each one by hand.

Happy to put the templates together in a PR if you're open to it.
