hooks(refactor): rename set_hooks_bulk -> set_hooks

why: Align with libtmux naming conventions (singular/plural pattern)
what:
- Rename method from set_hooks_bulk to set_hooks
- Update doctests to use show_hook().keys() instead of get_hook_indices
- Update module docstring bulk operations list

Squash target: d4de173 (hooks feat: add bulk operations)

 -------------------
 This module provides bulk operations for managing multiple indexed hooks:
 
-- :meth:`~HooksMixin.get_hook_indices` - Get list of existing indices for a hook
-- :meth:`~HooksMixin.get_hook_values` - Get all values as SparseArray
-- :meth:`~HooksMixin.set_hooks_bulk` - Set multiple hooks at once
-- :meth:`~HooksMixin.clear_hook` - Unset all indexed values for a hook
-- :meth:`~HooksMixin.append_hook` - Append at next available index
+- :meth:`~HooksMixin.set_hooks` - Set multiple hooks at once
