The snapshot geometry row enumerated what dropping
`apply_panel_cursor_icon()` from `reshape`'s tail would fire: "this row,
the menu row, and the line-number row below." Two panel rows have since
joined them, so the list read as exhaustive while being short by two.
Executed the mutation at this tree: it fires the two snapshot rows, the
line-number row, and both panel rows. The doc block now says so, and
says the list is expected to grow --- one hook reached by more routes is
the design, not drift, and a fixed enumeration would go stale at every
new one.
Verified: 12 B5 rows green; fmt, workspace clippy --all-targets
-D warnings, and git diff --check clean.
