"""Add board_program_cycles table — the Board Program registry's LEARN ledger.
One row per program cycle (roadmap, x_feature, and every later registry
entry). ``BoardProgramEngine`` dedups one open cycle per program off this
table (``closed_at IS NULL``) instead of each engine growing its own
open-cycle query, and accrues per-item approve/reject outcomes into
``decisions`` so the next cycle's exploration prompt can reference prior
rejections. Additive; inert until the Task-3 service starts writing to it.
Revision ID: 087_board_program_cycles
Revises: 086_enable_gemini_provider
