Giellie can already reach stock_items, but only through ad-hoc
list+adjust loops: a signed delta instead of an absolute count, no
batch call, fuzzy SKU picks the model cannot see are wrong, and
stock_items.adjust throws the actor away so the ledger row has no
attribution.
Adds a stock_items.set_quantities MCP tool that resolves each pasted
line (exact SKU, then description fuzzy), computes the delta, and
writes through updateStockItemsQuantities so the ledger is audited
against the signed-in user. Also mirrors price_list.stock_qty, which
price-list-service.ts documents as a denormalised snapshot of
current_qty.
The live data makes this matter: 522 of the 4,083 sellable items carry
a negative tracked quantity and 2,901 sit at zero. That drift is by
design - the till oversells on purpose (pos-service.ts:603) and is
corrected at the next stocktake, which is what this feature is.
Nothing blocks on low stock. One service flag (allowNegativeQty)
lifts the non-negative floor for the agent's writes only, leaving the
/stock page untouched.
