feat: implement Phase 2 (P1) protocol optimization — Federation, Multi-Agent, Driver Contract, Query Adapter

[Copilot]

Implements all four P1 sprints (3–6) from PROTOCOL_OPTIMIZATION_REPORT.md: GraphQL Federation schemas, AI multi-agent coordination, driver interface extraction to pure TS, and cross-protocol query DSL adapters.

GraphQL Federation (api/graphql.zod.ts)

• FederationEntitySchema with @key, @external, @requires, @provides directive schemas
• SubgraphConfigSchema — service URL, schema source (introspection/file/registry), health check, entity definitions
• FederationGatewaySchema — service discovery (static/dns/consul/k8s), query planning (parallel/sequential/adaptive), schema composition, error handling
• Wired into GraphQLConfigSchema.federation

AI Multi-Agent Coordination (ai/agent.zod.ts, ai/orchestration.zod.ts)

• Agent planning — 4 autonomous reasoning strategies: react, plan_and_execute, reflexion, tree_of_thought
• Agent memory — short-term (message/token budget), long-term (vector/db/redis persistence), reflection interval
• Agent guardrails — token budget, execution time cap, blocked topics
• MultiAgentGroupSchema — 5 orchestration strategies (sequential/parallel/debate/hierarchical/swarm), role-based members with dependency graph, inter-agent communication protocol (message_passing/shared_memory/blackboard), 4 conflict resolution strategies

const group: MultiAgentGroup = {
  name: 'code_review_team',
  strategy: 'hierarchical',
  agents: [
    { agentId: 'coordinator', role: 'coordinator', priority: 0 },
    { agentId: 'analyzer', role: 'specialist', dependencies: ['coordinator'] },
    { agentId: 'reviewer', role: 'critic', dependencies: ['analyzer'] },
  ],
  communication: { protocol: 'blackboard', maxRounds: 5 },
  conflictResolution: 'coordinatorDecides',
};

Driver Interface Contract (contracts/data-driver.ts)

• Extracted IDataDriver pure TypeScript interface mirroring all DriverInterfaceSchema z.function() signatures
• driver.zod.ts unchanged — Zod schema preserved for runtime validation, TS interface for implementation contracts

API Query DSL Adapter (api/query-adapter.zod.ts)

• RestQueryAdapterSchema — filter styles (bracket/dot/flat/RSQL), pagination/sort param mapping
• GraphQLQueryAdapterSchema — filter nesting styles (nested/flat/array), Relay pagination args
• ODataQueryAdapterSchema — v2/v4, string functions, $expand config
• QueryAdapterConfigSchema root + OperatorMappingSchema for cross-protocol operator translation

Report

• PROTOCOL_OPTIMIZATION_REPORT.md updated to mark all P1 items as completed

Tests: 58 new tests added (172 files, 4395 total — all passing).

Pull request overview

This PR implements Phase 2 (P1) protocol optimization, completing all four sprints (3-6) from the PROTOCOL_OPTIMIZATION_REPORT.md. It introduces comprehensive schema definitions for GraphQL Federation, AI multi-agent coordination, driver contract interfaces, and cross-protocol query DSL adapters. These additions elevate ObjectStack's protocol specification to support enterprise-grade distributed architectures and autonomous AI systems.

Changes:

• GraphQL Federation: Complete Apollo Federation v2 support with entity keys, subgraph configuration, gateway routing, and service discovery (4 discovery types, 3 query planning strategies)
• AI Multi-Agent Coordination: Agent planning (4 reasoning strategies), memory management (short-term/long-term with 3 storage backends), guardrails, and multi-agent groups (5 orchestration strategies, 4 conflict resolution approaches)
• Driver Contract Interface: Pure TypeScript IDataDriver interface (164 lines) separating type contracts from Zod runtime validation, maintaining backward compatibility
• Query Adapter Protocol: Unified DSL-to-protocol mapping for REST (4 filter styles), GraphQL (3 nesting styles), and OData (v2/v4) with customizable parameter naming
