Initial commit — memex

A compounding LLM-maintained knowledge wiki.

Synthesis of Andrej Karpathy's persistent-wiki gist and milla-jovovich's
mempalace, with an automation layer on top for conversation mining, URL
harvesting, human-in-the-loop staging, staleness decay, and hygiene.

Includes:
- 11 pipeline scripts (extract, summarize, index, harvest, stage,
  hygiene, maintain, sync, + shared library)
- Full docs: README, SETUP, ARCHITECTURE, DESIGN-RATIONALE, CUSTOMIZE
- Example CLAUDE.md files (wiki schema + global instructions) tuned for
  the three-collection qmd setup
- 171-test pytest suite (cross-platform, runs in ~1.3s)
- MIT licensed
