fix: reset renderer and cursor when releasing terminal

The cursed renderer moves the cursor between renders, which can cause
issues when the terminal is released and restored. For instance, when
we exec a command using tea.Exec, we want the cursor position to remain
the same after the command finishes and goes back to the same position
as before the command was executed.

With tea.Suspend on the other hand, we want to make sure we reset the
cursor position because the program stops executing and is put to
suspend. Resuming the program again initializes the renderer and its
cursor position again from scratch as if it was a new program.

This wasn't an issue for the standard renderer because we always put the
cursor at the lower left corner of the screen. Releasing and restoring
the program wasn't an issue because the cursor was always at the same
position.
