v0.5.6

The Agents git diff dock becomes resizable and scrolls each file on its own, and every diff surface in the app now draws from one color source. Cross-platform.

Added

• The Agents git diff dock is now resizable. Drag its left edge to widen or narrow it. The width is clamped between a readable floor and a window-friendly ceiling, so the dock can never swallow the terminal column or shrink below a usable code width.
• Each file in the diff dock now scrolls horizontally on its own, so a long line in one file no longer drags the short files into the blank. Files that overflow grow a per-file horizontal scrollbar (click the track or drag the thumb) and accept horizontal wheel scrolling, while vertical scrolling stays shared across the dock.

Changed

• Every diff surface now reads its +/- colors from one shared source. Codex green/red on dark themes, the theme's version-control colors on light themes. The Agents diff dock, the Diff/Review view, the CLI workspace sidebar diffstat and the diff sidebar previously each inlined their own hex and could drift apart; they now always match.
• The Agents environment toolbar's editor split-button now shares the rounded radius of the toggle buttons beside it.
