feat: Add branch name under worktree in session list (if different than worktree name) (#352)

* feat: show branch info in session sidebar and enrich worktrees

* feat: refresh sidebar branch display when switching branches in git menu

* fix: ensure branch name displays on mobile by fixing flex alignment

* style: make branch name font smaller, especially on mobile
