Implement `WhichKey` popup to show available command completions.
- Added `format_key_label` to convert `KeyCode` to human-readable strings.
- Added `binding_hints` to `Keymap` to extract available commands for a
given prefix.
- Added `src/ui/which_key.rs` for the widget implementation.
- Updated `src/ui/mod.rs` to export the new module.

Refactor AppMode to use MinibufferConfig for all text-entry modes. Update
command implementations to use new mode constructors. Introduce
PanelContent trait and replace panel structs with content types. Adjust
rendering to use Panel::new and minibuffer configuration. Update imports
and add MinibufferConfig struct. No functional changes; all behavior
preserved.

Add a tree-based category panel that supports expand/collapse of categories.
Introduces CatTreeEntry and build_cat_tree to render categories as
a collapsible tree. The category panel now displays categories with
expand indicators (▶/▼) and shows items under expanded categories.
CmdContext gains cat_tree_entry(), cat_at_cursor(), and cat_tree_len()
methods to work with the tree. App tracks expanded_cats in a HashSet.
Keymap updates: Enter in category panel now triggers filter-to-item.

Define Effect trait in ui/effect.rs with concrete effect structs for
all model mutations, view changes, navigation, and app state updates.
Each effect implements apply(&self, &mut App). Add App::apply_effects
to apply a sequence of effects. No behavior change yet — existing
key handlers still work as before.

Removes dead use statements across dispatch, formula, import, model, and
UI modules. Prefixes intentionally unused variables with _ in app.rs,
