fix(nvim): drop overseer task-bundle integration from auto-session

overseer.nvim removed save/load_task_bundle in the "task bundles get the
axe" refactor, which caused auto-session to error on every session restore:

    /lua/plugins/session.lua:27: attempt to call field 'load_task_bundle'
    (a nil value)

Remove the pre_save/pre_restore/post_restore hooks that called the removed
API. DAP breakpoint save/restore via save_extra_data is preserved.
