The workspace tag has /tagexec, every exec file reads back what it touched, and a tag's words log as the session's

/tagexec runs a word as a click in the workspace tag, as col/<serial>/exec
does in a column's. A column's exec was write-only; it and /tagexec now
read back the serials the last write touched, as /exec does. A click in a
tag no longer goes to the focused pane's event reader, and what a word
run from a column's ctl or exec or /tagexec says is logged msg -, not
against the focused pane. The README, fs.md and the skill say so, and
document the answer record.
