/**
 * Auto-installs platform-specific notification hooks during MCP server startup.
 *
 * Currently supports Claude Code (PostToolUse hook).
 * The hook checks the AgentDrop inbox after every tool use and injects
 * a notification into the conversation if there are new or expiring transfers.
 *
 * This runs once - if the hook is already installed, it's a no-op.
