hark-session

Hark's session flow for any work on a Hark project. Use when the Hark MCP tools are available and the work concerns a project (a V-### code, a brief, decisions, next steps, a handoff), or when a repo holds a .hark/project file. Read the brief with get_agent_brief before doing anything, work inside the accepted decisions, log as you go, and call end_session (or close_session) before you stop.
