Payment Delegation Parameter Validation And Schema Enforcement

MCP tool registration for Delegare agent payment delegation

Unique: Provides payment-domain-specific validation schemas with built-in support for common delegation constraints (amount limits, recipient whitelisting, time-based restrictions) rather than generic JSON schema validation

vs others: More secure than agent-side validation because it enforces rules at the tool boundary, while more flexible than hardcoded validation because rules are schema-driven and configurable
