docs: document copy-positive selection, Copy P&L, cache-based portfolio

Update the dev-facing docs so others can follow the current system:
- live/README: copy-positive-holder selection (replaces lead-time gate),
  Copy P&L as the copyability metric, new Paper portfolio (portfolio.py)
  + Dashboard feeds (watch_sharps.json / portfolio.json) sections, the
  full 8-step daily flow, the cache rolling-180d/replace retention gotcha,
  and a Copy execution (copybot/sync_floors, separate WIP) note.
- README: top portfolio is now precomputed off the cache (correct
  recycling), judge by Copy P&L not win%, copy execution is separate.
- FINDINGS: capital-recycling / $1k-book section + repo-layout refresh.
