Feature Description

The existing support for linked worktrees is suboptimal, it requires the user to know that the given repository is in fact a linked worktree which may be puzzling for someone who isn't aware of Git's internals.

A few ideas on improvements for this feature:

• Remove EnableDotGitCommonDir from PlainOpenOptions. This requires some consideration around the commonDir discoverability and whether users should have a way to determine what billy.Filesystem (or Loader) should be used for that.
• Ensure seamless experience across Plain and non-Plain APIs. The recently added x/plumbing/worktree.Open may need to be deleted and that logic moved to git.Open instead.
• Update documentation.
• Review worktrees example.

• Improved support for linked-worktrees (a.k.a. git worktree) #1808.
