ideas: editorial sweep — atomization, interlinking, restructuring

- Split competitive-analysis-2026-05.org → TOC + 9 competitor files in
  ideas/competitors/. Dropped date from filename. All competitor UUIDs
  generated, TOC keeps original UUID for backlink continuity.
- Deleted passepartout-economics.org archive (replaced by 27-node KB).
- Inlined 5 'See also' blocks into natural prose (compliance-index,
  first-mover-window, revenue-table, orders-of-magnitude-time,
  native-org-knowledge-base).
- Linked 7 orphan compliance pages back to compliance index + finished
  truncated sentences.
- Linked all 14 Agora requirement docs from topic-relevant pages
  (identity→lisp-machine-security, infrastructure→compute-marketplace,
  social-space→growth-strategy, exchange→agora-contracts, etc.).
- Linked ai-industry-impact from investment-thesis, sufficiency-flip,
  verification-appliance, effects-growth-flywheel (up from 1 to 10+ pages).
- Fixed CREATED timestamps to use git commit dates instead of today.
- Made all links absolute from root (no port inheritance).
- Removed stale agora/docs/ duplicate content.
