# tools/dotenv.ps1
# Unified .env reader function:
# - Supports `KEY=VAL` and `export KEY=VAL`
# - Skips blank lines and comments
# - Handles quoted values (single or double quotes)
# - Allows inline comments at the end of a line (space + #)
# - If the same KEY is defined multiple times, the last one takes precedence
