feat(aircoding): AirCoding V2 baseline — deterministic multi-agent architecture
Forked from OpenCode v1.17.4 with multi-agent system: - 5 agents: aircoding, scheduler, worker, architect, reviewer - Deterministic DAG scheduling engine (coordinator_tick) - Tool whitelists as hard enforcement - AirCoding validation plugin - System prompt injection for routing - V1 requirements: C4 docs, ADR, AGENTS.md, debug-log.md - Design documents in docs/
