Summary

Selecting a remote */HEAD entry in the branch dialog could create a local HEAD branch and trigger refname 'HEAD' is ambiguous.

  • Filter all remote HEAD symbolic refs from the branch list (retain, not a single remove)
  • Reject checkout_remote_branch for those refs
  • Derive the local branch name from the segment after the remote name (fixes /HEAD from origin/HEAD)

Closes #2681.

Test plan

  • cargo test -p asyncgit checkout_remote
  • Branch dialog → Remotes: no origin/HEAD (or upstream/HEAD) entry
  • Cannot create a local HEAD branch via the UI

fix(branch): block checkout of remote HEAD symbolic refs (gitui-org#2681
dfc00d2 
)

Hide remote `*/HEAD` entries from the branch list and reject checkout
attempts so gitui no longer creates a local `HEAD` branch.
