`td` is a Python CLI for tracking time on markdown todos identified
by ^tid block-refs, writing to a CSV at $TD_LOG (default ./time.csv).
Shell wrappers tstart/tstop/treport in .bashrc wrap it.
setup_env.sh gains deploy_bin() which symlinks every file in
dotfiles/bin/ into ~/.local/bin/, mirroring how deploy_configs
handles dotfiles.
