# iterm-map.sh — accurate "which iTerm2 windows belong to which project" map.
# Reads each session's live shell path (iTerm2 shell-integration `path` variable,
# reliable unlike the OS process cwd), resolves each to its git-repo root, and
# groups windows by project. READ-ONLY: touches nothing, moves nothing.
