bento-diffs Integration

bento-diffs is the diff rendering engine used by DIFF mode.

Integration model

• Imported as a Go library.
• Parses unified diffs.
• Renders ANSI-aware diff output for terminal UX.
• Embedded viewer footer is hidden so glib can use a single global footer.

Implementation constraints

• Preserve ANSI output end-to-end.
• Do not strip wrapper sequences required for styling.
• Keep navigation and chrome consistency inside glib shell.
