Pull #2325

github

Attach soft SoC commitments to their stock, not to a device index

Enabler for scoping #2194's SoC-constraint relaxation per stock:

- StockCommitment gains a 'stock' attribute holding the stock key; the
  StorageScheduler stamps it on all soft SoC commitments (soc-minima,
  soc-maxima, prefer-full).
- The solver couples stock-scoped commitments to the stock group as a whole
  (via the group's first device, whose stock is the group's stock), regardless
  of which device index the commitment names.
- DeviceInventory.stock_constraint_device(stock_key) exposes the device that
  applies a stock's SoC constraints, complementing stock_groups for
  deserialization-time scoping logic.
- The solver's grouped-device efficiency guard now tolerates a missing
  efficiency column (the default, lossless case), which direct callers of
  device_scheduler commonly omit.
