180932e1d9 Prevent multibuffer items from switching active repository (#58795)
Fixes the git panel's active repository being silently overridden by the
cursor position in `ProjectDiff`.

Closes #58792
Closes #61530

## Summary

When a multi-buffer item (e.g. `ProjectDiff`) gains focus, the workspace
calls `set_active_repo_for_path` with the cursor's project path to
automatically switch the active git repository. This was safe when
multi-buffer items returned `None` from `active_project_path`, but PR
#57236 changed `ProjectDiff` to return the cursor-based path (for
project panel highlighting), inadvertently allowing the cursor position
to override the user's explicit repository selection.

Fix the issue by restoring the `Singleton` guard that was removed in PR
#57236: only call `set_active_repo_for_path` when the active item is
backed by a single buffer.

## Changes

- **`workspace.rs`**: Only call `set_active_repo_for_path` when the
active item's `buffer_kind` is `Singleton`. Multi-buffer items (e.g.
`ProjectDiff`, diagnostics, search results) span multiple repositories,
so their cursor position should not trigger an automatic repository
switch.

  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
