Resolves https://github.com/zed-industries/zed/issues/57486

This diff fixes `g w` after selecting lines with `x` in Helix mode. `x`
leaves Zed in Helix normal mode with a non-empty selection, but jump
target collection treated non-visual selections as ranges to skip. As a
result, words on the selected line did not receive jump labels.

With this change, Helix normal mode keeps existing selection ranges
eligible for jump targets, matching Helix's behavior where normal mode
can still carry selections. The regression covers `x` followed by `g w`
targeting a word inside the selected line.

Release Notes:

- Fixed `g w` not targeting words on lines selected with `x` in Helix
mode.
