Nest single worktrees by branch path

[davdroman]

What problem does this solve?

“Nest Worktrees by Branch” only creates a group when a branch prefix contains multiple worktrees. With a single branch such as feature/tools/api, the worktree remains flat and the setting has no visible effect.

Proposed solution

Apply branch nesting to single worktrees. For example:

feature/tools
└── api

Single-component branches such as main should remain flat.

Alternatives considered

Continue showing the full branch path as one flat row.
