v0.22.1

Docs

• README now documents post-trade verify, self-heal, and their flags (--no-verify,
  --no-self-heal, --heal-passes).
• Clarified that protective stops are OPT-IN. The 0.20.0 --stop-pct note read as if stops are
  always applied; they are not. With no per-row stop_pct and no --stop-pct, no stops are
  placed, and a rebalance never strips an existing stop off a still-held position (only orphan
  stops with no position are cancelled). --stop-pct is a blanket default you opt into for feeds
  that omit stops but want every leg protected; a mixed book (e.g. some held-forever positions)
  should rely on per-row stop_pct instead.

Tests

• Added opt-in coverage: no stop_pct anywhere → zero stops placed; a held position's existing
  stop survives a no-stop_pct rebalance.

What's Changed

• docs+test(stops): document verify/self-heal; clarify stops are opt-in (0.22.1) by @markudevelop in #3
