/**
 * Mode profile storage for AgenticROS.
 *
 * Profiles live at ~/.agenticros/profiles/<mode>.json. The active profile is
 * copied into ~/.agenticros/config.json (which is what every adapter actually
 * reads). Swapping profiles is what `agenticros config use <mode>` (and the
 * up-runners) does so users can flip between real-robot and simulation
 * without hand-editing JSON.
 *
 * Why profiles instead of a single config: the real robot and the sim AMR
 * have different namespaces, transports, safety limits, and camera topics.
 * Tracking both in one file requires the MCP server to know "which mode is
 * active right now," which is exactly the problem `.mcp.json` env override
 * already tried to solve - badly, because env vars unconditionally win and
 * silently break the other mode. With profiles + a live ~/.agenticros/
 * config.json, everything reads from one place; the CLI just swaps it.
 *
 * Profile bootstrap policy:
 *   * On first use, if ~/.agenticros/config.json exists but no profiles do,
 *     we treat the current config as the user's last-used mode and seed
 *     profiles from defaults for both modes (preserving any namespace the
 *     user already had for whichever mode matches it).
 *   * Otherwise we write the canonical defaults below.
