Tutus Development f03564d676 Add free GAS for Vita holders with cross-chain fee splitting 
Rename PersonToken to Vita (soul-bound identity token) and implement
fee exemption system for citizens:

- Add Federation native contract for cross-chain Vita coordination
  - Visitor registry for Vita holders from other chains
  - Configurable visiting fee percentage (default 50%)
  - Inter-chain debt tracking for settlement between chains

- Modify GAS contract to burn fees from Treasury for Vita holders
  - Local Vita: 100% paid by local Treasury
  - Visiting Vita: Split between local Treasury and inter-chain debt
  - Deficit tracking when Treasury is underfunded

- Update mempool and blockchain to skip fee checks for Vita exempt users
  - Add IsVitaFeeExempt() to Feer interface
  - Modify verifyAndPoolTx() to allow zero-fee transactions

- Rename PersonToken -> Vita across codebase
  - Update state, native contract, and tests
  - Maintain same functionality with clearer naming

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

Tutus Development 99ba041a85 Add PersonToken native contract for soul-bound identity tokens 
Implements PersonToken as a native contract following NeoGo patterns:

Core Token Lifecycle (Phase 1):
- register: Create new PersonToken with owner, personHash, isEntity, recoveryHash
- getToken/getTokenByID: Retrieve token by owner address or sequential ID
- exists/totalSupply: Check token existence and get total count
- suspend/reinstate: Committee-controlled token status management

Attribute Management (Phase 2):
- setAttribute/getAttribute: Manage identity attributes with attestation
- revokeAttribute/verifyAttribute: Attribute lifecycle management

Passwordless Authentication (Phase 3):
- createChallenge/fulfillChallenge/verifyAuth: Challenge-response auth flow

Key Recovery (Phase 4):
- initiateRecovery/approveRecovery/executeRecovery/cancelRecovery
- Multi-approval recovery with configurable delay

Cross-Contract Integration (Phase 5):
- validateCaller: Verify calling contract has valid PersonToken
- requireRole: Check caller has specific role assignment
- requireCoreRole: Check caller has core role (User/Verified/Committee/Attestor/Recovery)
- requirePermission: Check caller has resource/action/scope permission

Files added:
- pkg/core/native/person_token.go: Main contract implementation
- pkg/core/state/person_token.go: State structs with serialization
- pkg/core/native/native_test/person_token_test.go: Test coverage
