Alessandro 58a5f8276b Add right canvas diff viewer
Adds the core _diff_viewer plugin for viewing staged, unstaged, and untracked working-tree changes in the right canvas and window modal.

Includes context-aware workspace resolution, safe read-only Git collection, zero-line .gitkeep filtering, unified diff rendering, and focused diff collection tests.
