Enable linefeed mode so newline moves cursor to column 0

remorses · remorses · commit 86ebd9c0a75f · 2025-11-27T15:35:36.000+01:00
Without linefeed mode enabled, \n only moves the cursor down without
returning to column 0. This causes text to display in a staggered pattern
instead of properly aligned at the left margin.

This fix sets the linefeed terminal mode to true when creating a new
terminal instance, making \n behave as expected (LF + CR).
