/**
 * cli-hook-startup.ts
 *
 * Called by Claude Code's UserPromptSubmit hook on every user message.
 * Replaces the former hmem-startup.sh bash script — works cross-platform (no Git Bash needed on Windows).
 *
 * Behavior:
 * - First message: remind agent to call read_memory()
 * - Every N messages: checkpoint reminder (remind mode only)
 * - After 60 messages: context warning (every 5 messages)
 *
 * Reads hook JSON from stdin, outputs hook JSON to stdout.
 *
 * Usage: hmem hook-startup
 *
 * Requires env:
 *   HMEM_PATH        — path to .hmem file (auto-detected)
 *   HMEM_PROJECT_DIR — directory for config + company.hmem
