skill: which pane am I, and how not to land in somebody else's tab

The skill described the API and left the one question an agent actually
gets wrong unanswered. It now leads with it: your pane is $SLOSH_PANE,
`focused` is the human's, and the fallback when the environment is scrubbed
is `pid` -- never focus.

The rest follows the verbs that shipped with it: `capture` for reading a
pane in any tab, `raw id` for typing into one, `apply-layout focus:false`
and `move-pane beside` for building work beside yourself without dragging
the view along.
