view.rs

//! Main view entry point — builds the top-level layout shell and delegates to
//! feature views for each region of the UI.
//!
//! Layout (when a repo is open):
//! ```text
//! ┌──────────────────────────────────────────┐
//! │  header toolbar                          │
//! ├────────┬─────────────────┬───────────────┤
//! │        │                 │               │
//! │ side-  │  commit log     │  diff viewer  │
//! │ bar    │                 │               │
//! │        │                 │               │
//! ├────────┴─────────────────┴───────────────┤
//! │  staging area (unstaged | staged | msg)  │
//! ├──────────────────────────────────────────┤
//! │  status bar                              │
//! └──────────────────────────────────────────┘
//! ```
//!
//! All vertical and horizontal dividers between panes are **draggable** — the
//! user can resize the sidebar, commit-log, diff-viewer, and staging area by
//! grabbing the thin divider lines and dragging.
//!
//! The outer-most widget is a `mouse_area` that captures `on_release` events
//! unconditionally, and `on_move` events **only while a drag is in progress**.
//! This avoids firing `PaneDragMove → update() → view()` on every cursor
//! movement when no resize drag is active.
