v0.2.0 - addressed multi-agent messaging

Initial public release.

Core: MCP server (C#/.NET 8) exposing Azure Storage Queues as an addressed agent-to-agent message bus. Inbox-per-agent, envelope contract (task/result/question/progress/info) threaded by conversationId, at-least-once delivery with explicit ack.

Operations: --peek CLI mode for zero-LLM polling, heartbeats in queue metadata, agents_health mesh diagnostics, watcher scripts (worker / orchestrator / notify-only) with persistent background sessions, live run viewer, human takeover & handback.

Batteries included: Claude Code skills (agent-delegate, agent-inbox, agent-health, agent-session), step-by-step trigger setup, field-tested troubleshooting, security guide (storage firewall pattern incl. the same-region VNet gotcha).

CI: full E2E over real MCP stdio against Azurite on every push.
