multiworkspace: Don't destroy workspace when git worktree is detached head (#51977)

When a git worktree is in a detached HEAD state (e.g. after `git
checkout --detach`), the workspace for that worktree would disappear
from the sidebar UI, and if the workspace was currently open your UI
would just disappear.

This happened because `parse_worktrees_from_str` silently dropped any
worktree entries without a `branch` line in the porcelain output, which
cascaded through the `linked_worktrees` list and caused
`prune_stale_worktree_workspaces` to remove the workspace.

This PR:
- Makes `Worktree::ref_name` an `Option<SharedString>` so detached
worktrees can be represented
- Renames `Worktree::branch()` to `Worktree::display_name()`, which
returns the branch name when available or the short SHA as a fallback
(mirroring how the title bar already handles detached HEAD for
repositories)
- Updates `parse_worktrees_from_str` to include detached and bare
worktree entries instead of dropping them
- Filters detached worktrees out of the worktree picker UI, preserving
the existing product decision to only show branch-based worktrees there
