Pixcode v1.39.1

Pixcode v1.39.1 is a layout hotfix for the chat and orchestration screens.

Fixed

• Chat composer stays pinned to the bottom of the chat frame without depending on the old Command Center rail.
• Chat messages keep the scrollable area above the fixed composer.
• Orchestration keeps a stable full-height frame so mobile/tablet scrolling is not blocked by nested panes.
• Command Center is now a normal top navigation item named Changes.
• Quick Settings no longer owns the Command Center enable/disable toggle.
