Zerg and ZTC

Zerg is a spec-driven framework for autonomous coding agents, and ZTC is its terminal client. My work includes parallel tool dispatch so agents stop queueing behind each other, background sub-agents for work that outlives a single turn, worktree-isolated batch execution so concurrent writers do not collide, a sandboxed multi-agent workflow runtime, MCP and provider routing, and the live web interface. People can watch a run as it happens.
