pax 095942c524 popout/hyprland: extract _hyprctl_* helpers with re-export shims
Pure refactor: moves the three Hyprland IPC helpers
(_hyprctl_get_window, _hyprctl_resize, _hyprctl_resize_and_move)
out of FullscreenPreview's class body and into a new sibling
hyprland.py module. The class methods become 1-line shims that
call the module functions, preserving byte-for-byte call-site
compatibility for the existing window.py code (_fit_to_content,
_enter_fullscreen, closeEvent all keep using self._hyprctl_*).

The module-level functions take the window title as a parameter
instead of reading it from self.windowTitle(), so they're cleanly
testable without a Qt instance.

Two reasons for the split:

1. **Architecture target.** docs/POPOUT_ARCHITECTURE.md calls for
   popout/hyprland.py as a separate module so the upcoming Qt
   adapter rewrite (commit 14) can call the helpers through a clean
   import surface — no FullscreenPreview self-reference required.

2. **Single source of Hyprland IPC.** Both the legacy window.py
   methods and (soon) the adapter's effect handler can call the same
   functions. The state machine refactor's FitWindowToContent effect
   resolves to a hyprland.resize_and_move call without going through
   the legacy class methods.

The shims live in window.py for one commit only — commit 14's
adapter rewrite drops them in favor of direct calls to
popout.hyprland.* from the effect application path.

Files changed:
  - NEW: booru_viewer/gui/popout/hyprland.py (~180 lines)
  - MOD: booru_viewer/gui/popout/window.py (~120 lines removed,
    ~20 lines of shims added)

Tests passing after this commit: 81 / 81 (16 Phase A + 65 state).
Phase A still green.

Smoke test:
- FullscreenPreview class still imports cleanly
- All three _hyprctl_* shim methods present
- Shim source code references hyprland module
- App expected to launch without changes (popout open / fit / close
  all go through the shims, which delegate to the module functions
  with the same byte-for-byte semantics as the legacy methods)

Test cases for commit 14 (window.py adapter rewrite):
  - Replace eventFilter imperative branches with dispatch calls
  - Apply effects from dispatch returns to widgets
  - Manual 11-scenario sweep
