v0.50.0

Highlights

• The workspace adapts to smaller windows with a repository drawer, responsive panels, resizable columns, and scrollable dialogs. History graph alignment now follows visible columns.

Fixes

• Githead rechecks generated commit plans after working-tree changes. Unchanged hunks stay available for Quick Commit, while changed or missing hunks make the plan stale.

Internal changes

• AI generation reduces redundant provider checks, batches commit-plan file reads, shares concurrent status lookups, and handles cancellation more safely.
