jackyu66gitandCursor 276481e02c feat(ECR-007): Wyckoff Live Structure with Confirmed/Live isolation
Add live.py lifecycle and event candidates; assemble confirmed vs live
in engine; Summary partition; execution_signal source=confirmed only.
Keep strategies untouched; do not lower Confirmed thresholds for Live.
