♻️ refactor(cli): rename command to sub_command for clarity

- rename `command` field to `sub_command` in `Cli` and `ConfigCli` structs
- rename `Commands` enum to `SubCmds` to reflect its role as subcommand
- update references to the renamed fields and enum variants
- this improves code readability and avoids confusion with other command concepts

- rename `set_command` to `set_action` in `EolRule` struct
- update references in `config.rs` to use the correct method name
- this fixes a bug where the eol action was not being set correctly
