# CONTAINER INITIALIZATION SCRIPT
# ============================================================================
# Purpose:
# This script is run when the dev container is created for the first time.
# It handles all first-run setup tasks to ensure a fully working environment.
#
# Tasks performed:
#   1. Install npm dependencies (if not already done)
#   2. Wait for PostgreSQL to be ready
#   3. Wait for Redis to be ready
#   4. Initialize the database schema
#   5. Seed the database with development data
#
# Usage:
# This script is called automatically by devcontainer.json's postCreateCommand.
# It can also be run manually: ./scripts/docker-init.sh
# ============================================================================
