History
Tutus Development 86f5e127c0 Add VTS (Value Transfer System) native contract 
VTS is programmable money with spending restrictions and automatic tax
accounting, designed to replace GAS as the primary user-facing currency.

Key features:
- NEP-17 compliant token (symbol: VTS, decimals: 8)
- Spending category restrictions (Food, Shelter, Medical, Education, Transport)
- Vendor registration and management
- Restricted VTS can only be spent at matching vendor categories
- Automatic tax withholding via payWage()
- Transaction recording for tax reporting
- Tax summary queries (getTransactions, getIncomeForPeriod, getTaxWithheld,
  getDeductibleExpenses, getTaxSummary)

Files added:
- pkg/core/native/vts.go: Main VTS contract implementation
- pkg/core/state/vts.go: VTS state structures (VTSBalance, Vendor, TaxConfig, etc.)
- pkg/core/native/native_test/vts_test.go: Comprehensive test suite

Files modified:
- pkg/core/native/contract.go: Added IVTS interface and VTS() accessor
- pkg/core/native/nativenames/names.go: Added VTS constant
- pkg/core/native/nativeids/ids.go: Added VTS ID (-14)
- pkg/core/native/nativehashes/hashes.go: Added VTS hash
- pkg/core/native/native_test/management_test.go: Updated test fixture
