//! View / filter / column management — pure-state commands that
//! manipulate `App` fields (`hidden_cols`, `saved_views`,
//! `named_filters`, `filter`) and persist the result to `state.toml`.
//! No AWS calls, no async spawns; ideal candidate for the third slice
//! of the `execute_command` split.
//!
//! Same parent-module-visibility pattern as `cmd_overlay` and
//! `cmd_write`. `encode_view` and `apply_view` are private free
//! functions in `app.rs`; the sub-module reaches them via `super::*`.
