The root cause was isExternalBeadsDir() incorrectly identifying bare repo
worktrees as "external" repos. This caused bd sync to take the "external
beads dir" code path instead of the worktree-based sync branch path.
The bug: isExternalBeadsDir() compared syncbranch.GetRepoRoot() (which returns
incorrect values for bare repo worktrees) with getRepoRootFromPath() (which
uses --show-toplevel). These returned different values for bare repo
worktrees, causing local worktrees to be treated as external.
The fix: Use git rev-parse --git-common-dir for comparison instead of repo
root. This correctly identifies that worktrees of the same repo share the
same git directory, regardless of bare repo setup.
Also added:
- getGitCommonDir() helper function
- Tests for both getGitCommonDir and isExternalBeadsDir
