improve: enhance llms-maintainer with spec-compliant format and framework detection (#563)
- Fix llms.txt skeleton to use official Markdown spec (H1, blockquote, H2 sections, link entries) - Fix page entries to use standard `- [Title](url): description` format instead of invented key:value - Add framework detection step (Astro, Nuxt, Next.js, Svelte, Hugo) to determine output path - Add `model: haiku` to frontmatter for cost-efficient deterministic scanning - Add `maxTurns: 20` to prevent runaway iteration on large sites - Remove unconditional `git push` — commit only by default, user pushes manually - Expand "AEO" to "AI Engine Optimization (AEO)" on first use in description and closing line Automated review cycle | Co-Authored-By: Claude Code <noreply@anthropic.com>
