ForgeFlow 0.4.4

Correct Git change handling

Deleted files are staged with git add -A and are removed from Gitea after commit and push.
Renames include both the new path and original path when staging or unstaging selected changes.
A failed staging action always reloads the real repository state so changes remain visible.
When commit succeeds but push failed, ForgeFlow clears obsolete file selection and shows the clean working tree as an ahead branch with a dedicated retry push action.
Added real bare-remote regression tests for deleted files, renames, and push-after-commit failure recovery.
