Module log_update 

Inline rendering with line tracking and erasure.

This is the clever bit that makes Blaeck different from fullscreen TUIs.

LogUpdate enables Ink-style inline rendering by:

1. Tracking how many lines were written in the previous render
2. On re-render: move cursor up N lines, erase each line, write new content
3. Remembering the new line count for next time

ANSI sequences used:

• ESC[nA — cursor up n lines
• ESC[2K — erase entire line
• ESC[0G — cursor to column 0

This creates the illusion of in-place updates without alternate screen mode.

Based on Ink’s log-update.ts. See refs/ink/src/log-update.ts for the original.
