2025-05-26kernel: cons: Fix newline caused by excessive '\b'Ian Moffett
Before this commit, if you were to write out too many backspace characters, it would result in an integer underflow for the scr->curs_col and scr->ch_col state resulting in the console logic assuming the cursor has gone too far off the screen which would cause behavior similar to as if you wrote out a line-feed character.

2025-05-22kernel: Optimize console & loggingQuinn Stephens
* Modified draw loops to use `fbdev_get_index()` less often. * Created `cons_fast_putch()`, then used it to implement `cons_putch()` and `cons_putstr()`. This way, when printing an entire string, the lock acquire/release and cursor hide/show will only happen once, instead of once per character. * Modified `syslog_write()` to use `cons_putstr()`.
