 3# smart-reindex.sh - Intelligently reindex mu database
 4#
 5# Automatically detects if mu4e is running and chooses the appropriate method:
 6# - If mu4e is running: Uses emacsclient to trigger (mu4e-update-index)
 7# - If mu4e is not running: Runs mu index directly
 8#
 9# Returns:
10#   0 - Reindex successful (or triggered successfully)
11#   1 - Reindex failed
12#
13# Usage:
14#   smart-reindex.sh
15#   smart-reindex.sh --verbose
