Add Mac Mini digital-employees blog post + site updates

[prasadus92]

Summary

• New Engineering post: Building Toward a Team of Digital Employees on a Mac Mini: Hermes Agent, Claude Code (ACP), and gbrain. ~3,200 words. Covers the stack, three upstream bugs I chased (Hermes Gemini auth regression, Hermes WhatsApp PLATFORM_HINT, gbrain hardcoded OpenAI embeddings), and where this is heading.
• Site-wide AEO/SEO hygiene across the 9 existing posts: BlogPosting JSON-LD + canonical URL on every post (and fixed a single-quote JSON-validity bug from an earlier automated pass — all 11 JSON-LD blocks now parse).
• SnowOptix restructured to Jan 2024 – Oct 2024 in the homepage experience card, llms.txt, and README.md, with a rewritten blurb reflecting wind-down at Luminik's start.
• Homepage blog grid now auto-sorts cards by data-date so the newest post always leads, even if HTML order drifts.
• New post propagated to llms.txt, sitemap.xml, homepage card, blog index, and reverse-interlinks in gstack-solo-builder.html and building-alone-in-2026.html.
• Added .gitallowed to whitelist two narrow git-secrets false positives on the RSA Conference proper noun.

New artefacts

• blog/dedicated-mac-mini-solo-startup.html
• assets/images/blog/alfred-luminik-differentiators.png — real Slack screenshot of Alfred answering a positioning question via mcp_gbrain_query with cited source docs

Upstream references cited in the post

• Hermes Agent: PR #11961 (regression), PR #12204 (revert attempt, my repro comment), PR #12251 (merged fix), Issue #12224 (open, WhatsApp markdown)
• gbrain: PR #89 (open, Gemini embeddings support)

Test plan

• Preview locally: python3 -m http.server 8000 at repo root
• Verify homepage lead card is the new post with Apr 2026 date
• Verify blog index shows the new post at top with 15-min read-time
• Verify SnowOptix experience card reads "Jan 2024 - Oct 2024"
• Verify Alfred screenshot renders in the Cross-session memory subsection
• Run a JSON-LD validator on the new post (expect 2 blocks: BlogPosting + FAQPage)
• Spot-check two existing posts for BlogPosting JSON-LD and canonical URL
• Merge deploys via GitHub Pages → verify live at prasad.tech after propagation
