refactor: improve command options and key bindings

- Rename -f flag from "flush cache" to "force sync" (implies -s)
- Add new -c flag for "clear cache" functionality
- Change fzf key bindings from Ctrl to Alt (u/p/t/l) to avoid conflicts
- Fix shell quoting and remove debug output
- Update help text and logging messages
