v0.5.10

Paneflow 0.5.10

A small polish release for the diff and Agents views. It restores per-file horizontal scrolling after the shared diff renderer refactor and keeps the Agents environment toolbar out of the CLI content.

Fixed

• Per-file horizontal scroll is back in the diff body. Each file in the Agents diff dock and the Review column owns its own horizontal offset again, after the shared direct-paint DiffElement migration temporarily dropped the old dock-specific behavior. Long lines can be reached per file with Shift+wheel or a trackpad horizontal swipe while native vertical scrolling stays untouched.
• The Agents environment toolbar no longer covers the CLI. The model selector and layout toggles now sit in a reserved top band, so narrow windows or a resized right diff panel cannot make the floating toolbar paint over the first terminal lines.

Changed

• Added shared diff horizontal-scroll geometry in diff/hscroll.rs, reused by both the Agents dock and the Review column.
• Added per-file span metadata to the shared diff row model so horizontal bounds are computed once off the render path.
• Restored persistent horizontal offsets for the Agents diff dock, aligned by file position across collapse and split/unified view changes.
