Stefan Haller bd6081d601 Select the checked-out branch via a refresh intent, not off-thread
Operations that check something out (checkout, create branch, move
commits to a new branch, fetch-and-checkout) selected the newly
checked-out branch by calling SelectFirstBranchAndFirstCommit() before
the refresh and passing KeepBranchSelectionIndex so the refresh wouldn't
override it. That set the selection directly, usually from a worker
goroutine (WithWaitingStatus/WithInlineStatus). Now that the refresh's
own selection write is bounced onto the UI thread, the two writes could
land in either order, and under load the refresh's "restore the
previously-selected branch" write would win — leaving the old branch
selected instead of the new one (flaky
move_commits_to_new_branch_from_base_branch).

Replace it with declarative selection intents applied inside the
refresh's own bounce, so the selection is set on the UI thread and
atomically with the list write (no off-thread write, and no BLOCK_UI
needed to avoid a flicker):

- BranchSelection: SelectCheckedOutBranch selects the checked-out branch
  (top of the list). The default, KeepBranchSelectionByName, restores
  the previously-selected branch by name as before. This replaces the
  KeepBranchSelectionIndex bool.
- CommitSelection: SelectHeadCommit (already existed) for the commit.
- SelectTopReflogCommit selects the top reflog entry, since a checkout
  adds a new entry there (reflog/checkout relies on this).

SelectFirstBranchAndFirstCommit is gone. The previously-selected branch
is now read at the top of the branches bounce, before the list is
overwritten, so that read moves onto the UI thread too.

fetchAndCheckout's refresh changes from ASYNC to SYNC so its
post-refresh focus switch can run in Then on the UI thread; SYNC keeps
the inline fetch spinner spinning (only BLOCK_UI would freeze it).
