Second Tier-2 battery, plugging into run.Ports.Budget: - budget.go: skillexec's BudgetTracker / NoOpBudget / DBBudget moved clean (stdlib only). Check/Commit match run.Budget exactly (compile-time proof in run.go: NoOpBudget and *DBBudget are run.Budget). - storage.go: the BudgetStorage seam + SkillBudget domain, split out of mort's GORM file (the GORM impl stays in mort). - memory.go: NewMemory() — zero-dependency in-process BudgetStorage with the 7-day rolling-window rollover in Add. Tests: per-user cap enforced, window rolls over after 7 days, NoOp always allows. CI invariant: core imports ZERO from the budget battery.
