fix: use real terminal cursor for block mode 

Previously, block cursors were always drawn manually as part of the
selection/highlight rendering, which prevented terminal cursor effects
(like cursor trails) from working. This change makes block cursors
behave like bar/underline cursors by using the terminal's real cursor
for the primary selection.

- Skip rendering primary cursor in block mode when terminal is focused
- Let terminal handle primary cursor rendering for all cursor types
- Simplify cursor method to return actual cursor kind when focused

This allows terminal-based cursor effects to work with block cursors
while maintaining proper cursor visibility when the terminal is unfocused.
