docs: humanize documentation and update architecture

- content/about.md: Rewrite with first-person voice, remove
  "next-generation" and "craft tools that emphasize" patterns.
  Add personality ("probably more than it should").

- content/collab.md: More direct language, remove "find value in"
  and "broader community" hedging. Shorter bullet lists.

- AGENTS.md: Remove "state-of-the-art", update architecture tree
  to reflect current modules (config, feed, templates), fix
  stale config section to show actual site.toml usage.
