Add AI blog post on System 1 vs System 2 tasks

[Copilot]

This adds the requested Layer5 blog post on how AI System 1 and System 2 task categories differ, why that distinction matters in practice, and when a model optimized for one or both is the better fit.

• Content

  • Adds a new post at src/collections/blog/2026/09-16-ai-system-1-versus-system-2-tasks/index.mdx
  • Covers:
    • what System 1 and System 2 tasks look like in AI workflows
    • why the distinction affects model selection, reliability, and cost
    • when fast pattern-matching is enough vs when deliberate reasoning is worth the latency
    • how to think about informal “System 3” discussions without treating it as a settled category

• Structure

  • Uses the current Layer5 blog format with:
    • frontmatter for taxonomy and SEO
    • intro / outro wrappers
    • internal cross-links to related AI and open source posts
    • Blockquote, Callout, and CTA components

• Assets

  • Adds a generated raster hero image alongside the post:
    • src/collections/blog/2026/09-16-ai-system-1-versus-system-2-tasks/hero-image.jpg

• Example

  • The post includes a compact task framing like:

| Task shape | System 1 fit | System 2 fit |
| ---------- | ------------ | ------------ |
| Email or ticket triage | Excellent | Usually unnecessary |
| Multi-file refactors | Weak alone | Strong |
| Root-cause analysis | Risky alone | Strong |

• Fixes [Blog] AI System 1 versus System 2 Tasks #8076
