Words from the workspace and column tags run in the session's directory

A command or Tty run from the workspace tag or a column tag started in
the focused pane's directory, though those tags have none of their own.
As acme's row and column tags do, they now run in the session's
directory, where pardes started (Pardes.sessionDir); a pane's tag and
text keep the pane's. The same for /tagexec, a column's exec and ctl.
