Subject: [PATCH] feat: integrate file selection mode with application action
 stack for back navigation

Integrate the file browser's multi-item selection mode directly into the application's global `actionStack` navigation controller to provide native hardware and interface back-button support.

When users enter multi-selection mode (e.g., long-pressing a file or checking multiple items), pressing the hardware back button or triggering back-gestures previously caused the application to navigate away from the current folder entirely, losing active context. This update registers selection mode as an isolated state layer within the global `actionStack`.

* **Action Stack Registration:**
  * Upon entering selection mode, the file browser pushes a `fbSelection` state descriptor to `actionStack`.
  * The back action handler captures `fbSelection` events to intercept back navigation, clearing all checked items and exiting selection mode first before any folder pops occur.
* **Stack Lifecycle Cleanup:**
  * Implemented automatic cleanup hooks to pop or unregister the `fbSelection` entry from `actionStack` whenever selection mode is dismissed through UI confirmation, cancel buttons, or batch execution tasks.
