feat: runner v0.2 — external setup, skip support, +24 real-data cases

Add `external:<path>` setup type for read-only access to real config
dumps without copying. Tests gracefully skip (○) when path unavailable.

Add 12 meta-compile cases for previously uncovered types (AccountingRegister,
CalculationRegister, ChartOfAccounts, ChartOfCharacteristicTypes,
ChartOfCalculationTypes, BusinessProcess, Task, ExchangePlan,
DocumentJournal, EventSubscription, HTTPService, WebService).

Add 18 external cases for info/validate skills against real ACC 8.3.24
config dump (meta, form, skd, role, subsystem, cf).

Total: 283 tests, all passing.
