A shell command from the workspace's or a column's tag runs as a command pane in the session's directory, never typed into the terminal with the keyboard

A command clicked in a header tag, or written to /tagexec or a
column's exec, was typed into the active terminal when it sat at an
empty prompt, so it ran in that pane's directory and left no run or
exit record. It now always gets a command pane of its own in the
session's directory, as acme's row and column tags have no directory
but the session's. tags.md writes the rule down: pane words act on the
column's active pane, a column's words on the column, shell commands
as their own panes, and over 9P a pane's word is refused.
