fix(frontend): remove jitter when scrolling up during chat autoscroll (#646)

The chat area re-armed autoscroll whenever the user was within 100px of the bottom, so scrolling up during a streaming response fought the incoming content ticks and produced jitter.

Autoscroll now disengages on any upward scroll (direction-based, no distance threshold), re-engages when scrolled back within 2px of the bottom (tolerating sub-pixel rounding at fractional zoom levels, where the at-bottom residual can reach 1px), and ignores sub-1px upward movement so macOS elastic-bounce settling does not disengage it. Sending a message pins the view to the bottom even if the user had scrolled up to read earlier messages.
