* fix: harden v2 service boundaries * fix(sessions): validate observation configuration first --------- Co-authored-by: jarvis <jarvis@agents.realmroot.dev>
Replace the v1 Agent/Machine runtime and CLI architecture with the v2 Resource Server, AMA-backed projections, task lifecycle, session observation, BDD specifications, and a single-package layered codebase. BREAKING CHANGE: remove the v1 CLI, internal Agent/Machine runtime entities, workspace layout, and legacy runtime coordination APIs.
