/**
 * Hive orchestration extension for Pi.
 *
 * Installed globally and auto-discovered for every project, but it only
 * activates when the current project opts in by providing a
 * `.pi/hive/hive-config.yaml`. Without that file the extension registers
 * nothing — no tools, no commands, no hooks — so non-hive projects are
 * completely unaffected.
 *
 * When active, it loads a hierarchical team from `.pi/hive/hive-config.yaml`,
 * gives the visible session only delegation/coordination tools (it routes,
 * never edits), renders a live team tree, and records a JSONL conversation log
 * across the orchestrator and workers.
