[Feature] Feedback form for non-technical users

[t3chn]

What

Add a feedback/issue reporting form at /feedback so non-technical users can report bugs, request features, and ask questions without a GitHub account.

Why

skill7.dev targets a broader audience than just developers. Users who discover plugins through the marketplace need a low-friction way to give feedback. Currently the only path is GitHub Issues, which requires a GitHub account and knowledge of how issues work.

Proposed approach

• Frontend: Astro form component at /feedback page with type selector (bug/feature/question) and minimal fields
• Backend: Astro SSR endpoint POST /api/feedback that creates GitHub issues via API
• Auth: Fine-grained PAT stored in env vars (scope: repo:issues on heurema/skill7.dev)
• Anti-spam: Honeypot field + rate limiting (per IP)
• Target: POST https://api.github.com/repos/heurema/skill7.dev/issues with auto-labels

Issue body should match org-level template structure (bug_report.md, feature_request.md, question.md from heurema/.github).

Out of scope (v1)

• Turnstile/reCAPTCHA (add when spam becomes a problem)
• File upload / screenshots
• Duplicate detection
• Email notifications
