* feat: resume last picker in refactored picker_ui structure
Add ability to resume the last closed picker with full state (query,
results, cursor, mode) by adapting for the refactored module structure.
In the coordinator (picker_ui.lua):
- save_state_and_close() deep-copies picker state before closing
- restore_from_state() recreates UI from saved snapshot
- M.close() overrides the wired close to save state then call close_windows
- M.resume(), M.resume_find_files(), M.resume_live_grep() public API
- Per-mode saved state (find_files vs live_grep)
In layout_manager.lua:
- Extracted close_windows() as the low-level cleanup
- close() now delegates to close_windows()
In main.lua:
- find_files and live_grep support opts.resume
- M.resume() public API for :FFFResume command
plugin/fff.lua:
- :FFFResume user command
* chore: update
