refactor(zsh): stop renaming zellij tabs from the shell

The hand-rolled `N:dir:cmd` tab labels could never stay in sync:

- After session resurrection, tab names are restored from disk but no
  shell-visible event fires, so labels stayed stale until the user hit
  Enter to trigger precmd.
- After closing a middle tab, zellij renumbers surviving tabs but again
  emits no per-pane event, so the `N:` prefix on every tab to the right
  silently became wrong.
- Once a tab has a custom name, zellij's tab-bar plugin uses it verbatim
  — there's no way to keep the default `Tab #N` numbering while also
  injecting dir/cmd info. The only plugin that addresses this (vmaerten/
  zellij-tab-rename) requires zellij built from main.

Dropping the hooks restores zellij's built-in `Tab #N`, which is the
single label that stays correct across resurrect and renumber. The zsh
prompt already shows CWD inside the pane.
