# Notification Entrypoint
#
# This entrypoint orchestrates all Notification handlers when Claude Code sends notifications.
# Notifications are triggered when:
# 1. Claude needs permission to use a tool (e.g., "Claude needs your permission to use Bash")
# 2. When prompt input has been idle for at least 60 seconds (e.g., "Claude is waiting for your input")
#
# It reads JSON input from STDIN, executes all configured handlers, merges their outputs,
# and returns the final result to Claude Code via STDOUT.
